just gotta ask yourself what you want. I loved my ex, decided to do my own thing, which was hard at first, but I'm a lot happier now. I just recently started talking to her again after a year and a half, so we're cool now. And while some feelings did come back when I met up with her, they passed and I know that it's just the past. I'm actually starting something with someone new, that has promise. Personally, I say give the new girl a chance, you two broke up for a reason, it's up to you though.
