So about year and half ago I got with this girl at a party, we were kind of friends before that. However at that time she had a boyfriend and blamed me for the entire thing happening. As an AFC I fucked it up, was to clingy afterward and constantly apologizing and eventually we just stopped talking all together.

I've seen her at a couple parties since and each time I do see her, she always says hello, but me being an AFC I never took the chance to do anything and she had a boyfriend. Now though, she is not only single, but I have the knowledge of a trainee pua. So basically my question is how can I contact her and get her to talk to me if I haven't talked to her in ages? And seeing her in person is not an option as she never parties anymore and I'm out of school.

Thank you!
