I am twice divorced and have been judged and condemned by church deacons (and others) because of it. My first wife was never faithful to me. She left me twice, and I forgave her and took her back both times. However, when she said to me, "I won't change", that was when I gave up and divorced her. I never believed in sex with anyone to whom I wasn't married.
The second one after two weeks of marriage started sleeping on the sofa and criticized EVERYTHING I said and did. I was just thankful she couldn't read my thoughts. After more than 7 months of being constantly criticized I said to her, "You might as well start looking for some place else to live, and we'll end this farce." Two weeks later she moved in with her son from a previous marriage. I'm sure they resumed their screaming match that went on at my home. Their yelling drove me out of the house. The thing is, a pastor I knew wanted to warn me about her, and I wouldn't listen. We make our bed and then have to lie in it. Counseling did no good. She just decided that I wasn't good enough for her when she realized that I had faults, and she didn't.
I have no desire to be married again and don't want anyone. Whenever I get the asinine idea that I want someone, I remind myself of the emotional pain and misery I suffered. It quickly cures me of that thought.
