Muddle, Good article. Alot to think about. It is hard to compete with a fantasy. In the midst of my H's affair, he said a lot of mean things to me too. It made me feel like crap. I now realize that he was trying to justify things in his head. I backed off and he now seems to be coming around.
If getting a D is not what YOU want, then don't initiate it. Let your W hurl her angry words at you and let them roll off your back. You know in your heart they are not true and you are a good person. Focus on being the best person that you can be, for yourself and your son. After a while I bet your W will come to see you for who you really are. She will be amazed that you stood by her even when she was so awful. Hang in there bud!
