So far I have done the best I can. I deleted messages from her, avoid checking her out on FB (we aren't FB friends) but sometimes find it difficult. I almost want to know she isn't with anyone but then realize it doesn't help my situation or if I did see someone with her it would make me feel worse.

I don't know this is hard to explain. I just feel terrible about my own looks, have never been one that is approached by women. I just am not sure how to make myself feel better, feel confident enough that I am better off with this person (she kind of ended it more or less and got all control).
