That is great news that H wants to do retro. I understand your timid reaction based upon his past conduct. I have not done it, but have heard good things about it both on this board and from few friends who attended. When is it going on by you? Is it a long wait? Hang in there. I don't think Retro can make the situation worse. No harm in going. Just try not to expect it to be the miracle cure. Even if it does benefit your R, there is still a ton of work to be done by both of you.
