I went through this too until I snapped out of it and started respecting myself-and demanding AH did too.
Actually, no I did not demand AH respect me because that's not possible. I cannot make anyone respect me. All i can do is choose who I spend my time with, who I spend my energy on in building a relationship, whether it's professional or personal.
So the real turning point for me was when I finally gave up on trying to figure out why AH behaved the way he does and started turning my time and energy towards myself. figuring out why I do the things I do and how to make my life better.
It's hard work, but it really pays off.
