Hi Free, I feel for you brother. I have so many things to say after reading your thread I will forget half of them. First, do NOT move out of the master bedroom and do NOT move out of the house. I said to my wife the first week this $hit storm blew into my life, if you don't want to live with me move out I not going anywhere. No discussion, just fact, not yelling, calm determined look. Some things I'm good at and others I stink. I have a great story on how I made sure my wife's EA/PA couldn't survive if you want to hear it. I have to be honest, I would not be strong enough to not talk to my wife about her PA, I would be compelled to talk with her. The longer it goes on the stronger their bond develops. Is the OM married?
Now is a time for deep thought on your part. What do you want? Is the PA a deal breaker? Can you live with this betrayal? I am happy to share my feelings about these questions but not before you answer. You have to decide what kind of picture you will paint. You referenced a child in a post, how many do you have and how old? gender doesn't matter.
I would not quit yet. You made me smile with this comment "there aren't many W on here as cold as she is". I'm going to sleep ttyl.
