In catching up here, I get the sense that H is just overwhelmed with guilt and he can't face it. He's giving it his best effort to project his guilt onto everyone else and especially you to try to ease his burden. He doesn't believe he is worthy enough to be with you. He's trying to relieve his guilt by trying to make you as guilty in his mind as he thinks he is. Its not going to work, but it seems he is determined to try.
I don't know what to recommend other than try to regroup and standing firm in expressing having no true interest in an R with any other man ... which is hard to do but keep at it and I know at the same time we do get lonely for companionship at times when we need it.
