Divorce is a rough thing to go through.
Yes it is, reasons for he divorce vary though, from sexual incompatibility, or lack of independence. 
That's interesting that you say lack of independence.  Why?
One or both spouses could have personality clashes. one or the other might want to hang out with just their friends more than the other partner. 
I see.  I would say infidelity is a big problem as well.
I would think so as well. Most people want exclusivity and these expectations are not always met. 
I also think communication (or rather the lack of thereof) is also an issue leading to divorce.
Domestic violence and sexual abuse are also other things that can lead to divorce. 
Sadly it is.  It often goes unnoticed.
yes, and in some Countries forced is not considered "rape"
