This is getting out of control. My ex who left me over 7 months ago has called me again after about 4-5 months of no contact at all. She has a new boyfriend who she has been with for probably 3-4 months. She tells me that she misses me, and that she can't come back to me because she's scared. She says she's "comfortable" where she is. She already knows full well that I'm a total fool for her, I don't know why she does this to me. Why can't we just let go?
