I had to crash this sorry Frank. This is the case for me and me only. Up until the time my wife said she is moving out. And up until the time, I would say about a year ago. Because from a year ago until now I really have been getting my act together and working on me and my life. But prior to that one year if she had OM I would have taken responsibility for it and tried to save the marriage. If in fact my situtation turned out like yours wher she turned into the chaser, I would have treated her just like your husband is treating you.
When you want to be with somebody and you love them and you feel partly responsible for driving them into the arms of another you will FIND a way to get over it. But that does not mean you will not be punishing that person if given the chance. The more you show your huband that you are hurting the more he will hurt you until he thinks you have had enough, and then and only then will he take you back. But if you show no hurt and say sorry and all that and you believe there is nothing more you can do and he knows there is nothing more you can do then it is you and the hurt he sees that makes him hurt you more. But in the end he knows he will come back. I promise you and this comes from a guy. If he believes that he is partly responsible for driving you away he will find a way to forgive you and come home. And if he is like me where OM signals the end, he would end it and end it quick. I am sure there are parts missing in the post but try to see the whole picture.
Go ahead and take a poll, AmyC. Guys are different, it is much more black and white. But hey I cant speak for anyothers, I can only speculate. But IMO for your situation dont give up.
