I don't feel I'm reliant on her for me to be happy.
I guess the dilemma I have is that I feel like detaching is giving up. If I detach to the point where I stop trying to expect her to come around, I feel like that will be the point where I move on and stop trying. And I'm pretty sure if I stop trying, it's over because she is certainly not going to try.
If I let go of any expectation that she'll come around and we might get through this, why would I have any motivation to keep trying? I mean, as tempting as it is to just back off and tell her the ball is in her court, seems like when I try to do that she just sees it as more withdraw and more proof I don't care.
