Oh definitely Claire. But I will never feel sorry for them. I do pity them. Seeing her makes me see that it can't possibly work out and he clearly is filling a void to avoid working on his own issues. She is a bandaid. I actually wasn't even sad seeing her. I was angry yes but also thought - how pathetic.
I will tell you this from a guy who has used a relationship with another woman to get over a relationship I was in. I think it may apply because of your comment that your H is using her as a bandaid. In my case, I would go back to an ex, of if none were around, I would typically find one with flaws I knew I could not live with long term. The idea being that it would prevent me from becoming attached emotionally and allow me to walk away when I was ready. I am not saying that with any pride in my actions. It was wrong and unfair. I just wanted to give you a possible insight as to what your H motives might be with his OW. He must know the relationship will not endure, and perhaps that is WHY he chose her. I know I am not alone with my past actions because in my circle of guy friends we all did this. Keep in mind it was in our 20's, so this was 10-20 years ago for me. But even as 25 pointed out in my own thread, I have a tendency to regress to that line of thinking.
Best of luck to you
