Mojones, I hate to say this to you because I know it is painful. But you H is showing a lot of the same signs mine did when he got back into the affair with OW. Like your husband, mine came home and didn't want to talk about the affair at all (big red flag there). He threw himself back into painting and his artwork. I thought that was a very positive thing. Then suddenly one day he is done with the art and just sat in his chair hating everything and everyone. Shortly after that he was "going out" a little bit more and more. And sure enough OW was back.
The first thing you need to do is figure out if OW really is in the picture. You H could just be going through withdrawl and depression over the whole affair business.
Only you know if/when you should give up. I had my breaking point when I knew it was time to throw in the towel. But each sitch is different and each person is different. You have no need to give up now. Right now it is time to keep working. What are you doing to GAL? What are you doing to have a PMA? Focus on those things even though you really don't want to.
I will keep checking in on you, Sara
