Good luck bro. I could tell you kinda had your mind made up 20 posts ago. It seems like your asking permission from us or something. All signs that we see point to this ending badly again, but what the hell? We may all be wrong, and plus you only live once so if you get another crack at it, go for it. Try and stick some insulation between your feelings and her, this will add an edge of mystery about you that may just up your stakes :D At the very least you won't be hurt again if it all comes tumbling down.
Don't act like a lovesick wussy either, chicks don't like it. ie clingy. :cool:
Best of luck
