Divorce
Divorce, also known as dissolution of marriage, is the termination of a marriage or marital union, the canceling or reorganizing of the legal duties and responsibilities of marriage, thus dissolving the bonds of matrimony between a married couple under the rule of law of the particular country or state. Divorce laws vary considerably around the world, but in most countries divorce requires the sanction of a court or other authority in a legal process, which may involve issues of alimony (spousal support), child custody, child visitation / access, parenting time, child support, distribution of property, and division of debt.
Marriage
Marriage, also called matrimony or wedlock, is a socially or ritually recognised union between spouses that establishes rights and obligations between those spouses, as well as between them and any resulting biological or adopted children and affinity (in-laws and other family through marriage). The definition of marriage varies around the world not only between cultures and between religions, but also throughout the history of any given culture and religion, evolving to both expand and constrict in who and what is encompassed, but typically it is principally an institution in which interpersonal relationships, usually sexual, are acknowledged or sanctioned.
Divorce in Islam
Divorce in Islam can take a variety of forms, some initiated by the husband and some initiated by the wife. The main traditional legal categories are "talaq" (repudiation), "khulʿ" (mutual divorce), judicial divorce and oaths. The theory and practice of divorce in the Islamic world have varied according to time and place. Historically, the rules of divorce were governed by sharia, as interpreted by traditional Islamic jurisprudence, though they differed depending on the legal school, and in general, historical practices sometimes diverged from legal theory. In modern times, as personal status (family) laws were codified, they generally remained "within the orbit of Islamic law", but control over the norms of divorce shifted from traditional jurists to the state.
Divorce law by country
This article is a general overview of divorce laws around the world. Every nation in the world allows its residents to divorce under some conditions except the Philippines (though Muslims in the Philippines have the right to divorce) and the Vatican City, an ecclesiastical sovereign city-state, which has no procedure for divorce. In these two countries, laws only allow annulment of marriages. In Muslim societies, legislation concerning divorce varies from country to country. Different Muslim scholars can have slightly differing interpretations of divorce in Islam, (e.g. concerning triple talaq).
Agunah
Agunah (, plural: agunot (עגונות); literally "anchored" or "chained") is a halachic term for a Jewish woman who is "chained" to her marriage. The classic case of this is a man who has left on a journey and has not returned, or has gone into battle and is MIA. It is used a borrowed term to refer to a woman whose husband refuses, or is unable, to grant her a divorce document in Jewish religious law, known as a "get". For a divorce to be effective, Jewish law requires that a man grant his wife a "get" of his own free will. Without a "get" no new marriage will be recognized, and any child she might have with another man would be considered a "mamzer", a term often translated as (but dissimilar to the concept of) a bastard.
Grounds for divorce (United States)
Grounds for divorce are regulations specifying the circumstances under which a person will be granted a divorce. Each state in the United States has its own set of grounds. A person must state the reason they want a divorce at a divorce trial and be able to prove that this reason is well-founded. Several states require that the couple must live apart for several months before being granted a divorce. However, living apart is not accepted as grounds for a divorce in many states. The United States allows a person to end a marriage by filing for a divorce on the grounds of either fault or no fault.
Divorce in the United States
Like marriage, divorce in the United States is under the jurisdiction of state governments, not the federal government. Divorce or "dissolution of marriage" is a legal process in which a judge or other authority dissolves the bonds of matrimony existing between two persons, thus restoring them to the status of being single and permitting them to marry other individuals. The legal process for divorce may also involve issues of spousal support, child custody, child support, distribution of property and division of debt, though these matters are usually only ancillary or consequential to the dissolution of the marriage.

Oh no!  I am so sorry to hear that.  Hopefully it is happening on good grounds though.

Well let's just say that he broke the law by not being monogamous. 
In most countries, monogamy is required by law, so divorce allows each former partner to marry another person; where polygyny is legal but polyandry is not, divorce allows the woman to marry another person.

Monogamy
Monogamy ( ) is a form of relationship in which an individual has only one partner during their lifetime or at any one time (serial monogamy), as compared to polygamy, polyandry, or polyamory. The term is also applied to the social behavior of some animals, referring to the state of having only one mate at any one time. The term monogamy is used to describe for different relationships. Biologists, biological anthropologists, and behavioral ecologists often use the term monogamy in the sense of sexual, if not genetic, monogamy. Modern biological researchers, using the theory of evolution, approach human monogamy as the same in human and non-human animal species.
Monogamy in animals
Monogamous pairing in animals refers to the natural history of mating systems in which species pair bond to raise offspring. This is associated, usually implicitly, with sexual monogamy. Monogamy is defined as a pair bond between those of the same species. This pair may cohabitate in an area or territory for some duration of time, and in some cases may copulate and reproduce with only each other. Monogamy can be partitioned into two categories, social monogamy and genetic monogamy which may occur together in some combination, or completely independently of one another. As an example the cichlid species "Variabilichromis moorii" the monogamous pair will care for eggs and young together, but the eggs may not all be fertilized by the male giving the care.
Animal sexual behaviour
Animal sexual behaviour takes many different forms, including within the same species. Common mating or reproductively motivated systems include monogamy, polygyny, polyandry, polygamy and promiscuity. Other sexual behaviour may be reproductively motivated (e.g. sex apparently due to duress or coercion and situational sexual behaviour) or non-reproductively motivated (e.g. interspecific sexuality, sexual arousal from objects or places, sex with dead animals, homosexual sexual behaviour, bisexual sexual behaviour). When animal sexual behaviour is reproductively motivated, it is often termed "mating" or "copulation"; for most non-human mammals, mating and copulation occur at oestrus (the most fertile period in the mammalian female's reproductive cycle), which increases the chances of successful impregnation.
Social monogamy in mammalian species
Monogamous pairing refers to a general relationship between an adult male and an adult female for the purpose of sexual reproduction. It is particularly common in birds, but there are examples of this occurrence in reptiles, invertebrates, fish, amphibians, and mammals. Social monogamy in mammals is defined as a long term or sequential living arrangement between an adult male and an adult female (heterogeneous pair). It should not be confused with genetic monogamy, which refers to two individuals who only reproduce with one another. Social monogamy does not describe the sexual interactions or patterns of reproduction between monogamous pairs; rather it strictly refers to the patterns of their living conditions.
Infidelity
Infidelity (synonyms include: cheating, adultery (when married), netorare (NTR), being unfaithful, or having an affair) is a violation of a couple's assumed or stated contract regarding emotional and/or sexual exclusivity. Other scholars define infidelity as a violation according to the subjective feeling that one's partner has violated a set of rules or relationship norms; this violation results in feelings of sexual jealousy and rivalry. What constitutes an act of infidelity depends upon the exclusivity expectations within the relationship. In marital relationships, exclusivity expectations are commonly assumed although they are not always met.
Polygamy
Polygamy (from Late Greek , "polygamía", "state of marriage to many spouses") is the practice of marrying multiple spouses. When a man is married to more than one wife at a time, sociologists call this polygyny. When a woman is married to more than one husband at a time, it is called polyandry. If a marriage includes multiple husbands and wives, it can be called a group marriage. In contrast, monogamy is marriage consisting of only two parties. Like "monogamy", the term "polygamy" is often used in a "de facto" sense, applied regardless of whether the state recognises the relationship. In sociobiology and zoology, researchers use "polygamy" in a broad sense to mean any form of multiple mating.
Extra-pair copulation
Extra-pair copulation (EPC) is a promiscuous mating behaviour in monogamous species. Monogamy occurs when one male mates exclusively with one female, forming a long term bond and combining efforts to raise offspring together; extra-pair copulation occurs when one of these individuals mates outside of this pairing. Across the animal kingdom, extra-pair copulation is common in monogamous species, and only a very few pair-bonded species are thought to be exclusively sexually monogamous. EPC in the animal kingdom has mostly been studied in birds and mammals. Possible benefits of EPC can be investigated within non-human species, such as birds.
