My advice for you:
Move on
You are the F word to her (Friend)...there are a lot of women like that unfortunately, you notice how bad people usually seem to have a lover? Theres a reason for that, a lot of women (and men too) LOVE the challenge, or to chase, its almost like a drug to some
Just move on. For a long time I didnt think I was gonna settle down and get married and then we met. It came out of nowhere, so dont force it, be yourself and hopefully someday Mrs right will come along who will appreciate being treated well.
