I agree with Phreak looking at it from the standpoint of vanilla relationships.

Maybe there is some non-vanilla aspect of it that I am unable to grasp - say, you sometimes want to be dominated, so maybe submitting yourself to being rejected by her gives you the pleasure of being humiliated and slighted, which is akin to being dominated ??? perhaps, not sure since I do not understand the dynamics of such relationships at all.

But looking at it in a straightforwardly vanilla way, Phreak is right and you need to break up.
