Nate. She was messed up before you even met her. It is no failure on your part if she is mentally ill. You didn't do this, so you can't fix it.
Perfectionism will get you nowhere in future relationships, either. Lighten up, lower your standards for yourself.
Oh, and in case fish wasn't clear....forget about Amy. She is an absolute, worst-case, lost cause. Unfixable.
Me: 54 Her: 50 and sexy as hell M: 32yrs T: 34yrs Bomb: Sept 26-07 "lost our emotional connection" Bomb 2: Dec 25-07 she's "not feeling desire" She asked if she could come home Apr 26-08! Everything's GREAT!
