Sorry you are going through this. Sounds like my husband. He tells me constantly how we don't work but doesn't try to do work on our marriage. He's been married before. This is my first and only marriage...or so I thought (his parents have reached been married 3-4 times so that's his model). It really is hard to love and commit to someone only to have them reject you in the end. I think people can and do just flip without any advance warning. My husband sure did. Not saying things are perfect but I know I take marital vows seriously. For better or worse means something to me. It means little to others.
