I honestly don't know what the situation with her other ex is, though I suspect they are getting relatively close. That is not going to last though as he will fall back to his old ways after a matter of time.
I just don't understand my role in this all anymore. Why does she still reach out to me? Why does she still try to call me and make plans with me when she is seemingly always awkward and in a bad mood when we're together? Of course I want to get her back some day down the line, but what the heck is she thinking in the meantime?
Can any girls help? Why would someone do these things?
