In my despair, I broke down and contacted him last night to ask if his cat has recovered. It was innocent enough, but I also wanted to find out if he is dating, so I mentioned that I assumed he is dating because I haven't heard much from him and also mentioned it is fine if he is. He said no and how can he date right now, but I don't believe him - of course I don't believe him.
So I just gave him more supply and more ego boosting. I weakened and broke down.
