I hate to say this, but I'm not attracted to my wife at all.
Did this happen over time?
It's not about how she looks, It's about how shitty she behaves.
Oh, now I understand. Yeah, if she really behaves so badly that you are no longer attracted to her then being married to her no longer makes sense. You've stopped caring about her and unless you find a way to reconnect the marriage is destined to fail.
I know, I want a divorce.
While I get your desire for a divorce, I think it would be wise to try counseling as a couple first. You've put a lot into your marriage and I think you owe it to yourself and your wife to see if these issues are something that you can work through.
