Been on this train for 12 years. When we are not getting along he admits he fell out of love with me. When things are going well he says he fell back in love with me all over again. It just goes back and forth, back and forth.  It's my belief that when you love someone you can't just STOP loving them one day and then fall in love with them again a couple of days later. I understand how you can feel detached or unhappy with them but can you really just not love them anymore temporarily?
