As the "question title" says I left a girl around December she was my girlfriend for about 1 year, and on November/December we broke up and it's been around 5-4 months and now she's seeing someone, we both have seen other people but we both know we haven't found that special person, and yesterday I texted her talking about our relationship we haven't talked in 6 months our birthdays are 10 days apart from each other so obviously we both said to each other happy birthday etc, anyway yesterday I texted her talking about our past relation ship, and as it turns out she still has feelings, for me as I do for her, but "but" there's always a but, she's dating another guy, and it's kind of a funny story how the guy she is seeing, started talking to me and you know I didn't do anything to steal the girl he is going out with, you know I respect him, anyway while talking with her I asked her if she had an official boyfriend, and she said no, she just said that she could have waited a lifetime for me but now I decide to comeback. And I find myself asking what to do because I just told my good friend whom I known for a decade that I have a SMALL crush for her and I know for the fact that she has that same crush for me, but what's a crush against a love? Anyway can anyone give me suggestions on what to do?

You broke up for a reason... you should stick with it. Generally, getting back together after a breakup doesn't seem to last very long.

If it was me, I'd move on.

You broke up. She is with someone else. There no reason why you can't date other girls. Go out and have fun. If your ex really wanted to be with you instead of her current guy, she would be.
