BTW, in my case:
1. Too much arguing and fighting - her not me. Constantly complaining and bitching about my family, my friends, my work (in no particular order). She was seriously threatened by anyone and everything that she saw as competing for my attention. She felt that I had to make her THEE most important thing in her life. Couldn't handle it. She was a dictator and expected you to do what she said, when she said.
2. She was a slob. I'm not a neat freak, but I do keep things in order and pick up after myself. Shoes in every room of the house, clothes laying around everywhere, never threw anything out. Old bills from 2 years ago laying everywhere, never cleaned up the house. (It will drive you crazy.)
3. We both were unfaithful, but as someone else said, I was unfaithful by the rules - purely sex - MPs, casual hookups. Her's was an affair of the heart - whom she eventually married, so good for her, things worked out for her. (He's got more patience and understanding than I ever will.)
Never fought about money - till the end. Then it was a big fight.
Never fought about sex - infact, when we were splitting up, the sex was better than ever and in fact, she kept coming round to my bed for about a year after we split.
