there should be a forum for people driven by "the one" cuz i'm seeing more and more convo's lately about ex's. no problem with that, but now i just cringe about the whole thing cuz i think the whole soul mate thing and all that was such a facade.
when i finally woke up and saw the way things worked, then i was able to really focus on the advice and information given on this site. I really feel sorry for the people who still pine after an ex that dumped them for some other guy because he wasn't good enough, but "she's perfect" so he can't move on. Hate to sound like a dyck, but really love just messes with you. If you're not careful and can't control it, someone always gets burned.
typically you just get stuck thinking about that one person you had "history" with instead of focusing on the next step in your life. that chapter should be done and the best thing to do is see if you made mistakes and then correct them and move on.
now i pretty much just went on a rant there which probably doesn't apply to your situation, but it's good to know why it's best to move on and then move on. far too many guys i talk with find REASONS to LOOK for things to analyze, they just don't wanna look for someone new and it sucks to try and help someone that don't get it.
btw, funny how girls can be complete bytches like that. my ex gf told me a good 3 months ago to f' off cuz i jokingly left a message on her site about a band she likes coming to town.
