I'm in your boat. Mine was an EA and his wife found out. I knew at that point I needed to work on my M. I realized what the fog did to me. I was trying to be sweet. I bought marriage books and wanted to try to get closer to my DH. DH maybe thought I was being wierd so he asked me if I was having an A. I said EA, no sex. Maybe he believes me, maybe not. He asked who. I told him. He asked if I wanted to leave him and I said no. We both know our marriage had many issues and we've even talked about divorce.
That night he actually cuddled with me. And since then we've both been nicer, sweeter, especially me. I want him to know that I want to work on our m. He's made a few digs like 'hows your friend?" But I keep telling him its over and it was nothing. And maybe cause he thinks I ended it, it is telling him something.
My H and I have almost no sex. That is hard for me. He has never been interested. I am trying cause he is a wonderful man. I've begged him for years we need to work on our M but its always last on his list, between work, sports, buddies, hobbies. I guess I've felt like a maid more than a wife. My EA made me feel taken care of, cared about, for the first time in my life since marriage.
So right now, we are not talking about the EA. We are just being nice to eachother. Over time, who knows. But the sad thing is he didn't want to read the marriage books. I still don't think he wants to work on it. Maybe he doesn't love me, he just loves the life. Him working, me doing everything else.
