I could never do what your husband did. I could never walk. Sorry, I just can't justify that to myself. I really do believe in the permanence of marriage.
What is my #1 goal right now? To have an obituary, that shows that I was married when I die. Really, that's it. If I never have sex again, I can live with that.
So I will not do anything that will provoke a divorce. I will try to make improvements in myself, and make myself a better husband/father/Christian. Yes, I will look into the Al-Anon meetings.
But I have tried to take back my bedroom, and become more assertive in my marriage. That brought me to the edge of divorce two years ago. Sorry, I tried that, and it simply will not work with my wife. She insists on total, 100% control of our relationship.
