Don't wait for her. Live your life, the girl is doing that as she knows you are there as an option (especially if you have told her how you feel about her)get out meet new women. If this girl realises you aint no longer making her a priority she will either make moves to get back in you life or not give a f*ck and do her (meaning she wern't that into you in the first place).In short do you. If that means going on cold so be it.
