MB...there is NO REASON for you to feel embarrassed about the things you shared. You did nothing wrong. I was thinking the same thing as Wonka but didn't want to come right out and say it... H sounds like he has issues above and beyond typical relationship problems or MLC, etc.
I understand now why you seemed resistant to earlier suggestions about H having unmet needs and what you might need to do to fix that. I'm sure your H *does* have unmet needs, however the problem with individuals with personality disorders like NPD is, they are generally not healthy needs, so it's typically not possible for any normal human being to meet them no matter how hard they try. The relationship is parasitic...they will feed off of you and take, take, take, but give you little or nothing in return. Often, you get just enough to keep you hanging on, but never to have your own needs met or be happy.
BTW...it is textbook behavior for individuals with personality disorders to be exceptionally charming in the beginning. It's their hook.
