You will know when enough is enough. You need to look at the bright side of starting over. Yes, splitting up the house and going through all the red tape of divorce is a chore, but think about the enjoyment of finding someone out there that will actually treat you like a lady (and yes, they are out there). And, you have an advantage not having kids. If you divorce, you never have to see him again. With kids involved, you have to deal with your ex all the time. Like I said in your other post, my first wife was the devil. My current wife of 10 years is an angel and I see what I was missing in the years before I found her. We are working on some low desire issues with her, but the rest of our relationship is great. She is my best friend.
