If you really think about it, the only thing that's changed is you know about this guy's conversations with your H.
Read around the board here, some unflattering things are said about WASs. It's part of the process. This guy doesn't know you, you don't know if anything he says is true. Work at not taking it personally. Stop the mindreading.
I know you don't really want an opportunity for growth right now, but this is one. You are in control of you. Get out and do something, write out exactly what you would like to say to H and then burn it. Make a list of goals (not R goals) you'd like to attain in the next 6 months, things like go on a trip, read a certain book, see an act/play you've always wanted to, you have no restraints right now. Look into Meet Up groups in your area. Get a pedicure or a massage.
Take care of you, let H worry about his braggart friend.
Would doing, saying anything now get you closer to your goal?

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
