wow you guys are harsh.... sounds like some inside stuff that i'm not in on tho...
look man, stay away from girl A... never get back with a girl thats hurt you, especially when you have so much for her that you're hurt easily by her. its just trouble down the road.
girl b: **** her....... seriously.... like every night..... between classes.... whenever you can man
just have fun while you can, things change every day, and really you cant plan for ****. so just enjoy every day as it is, STOP LOOKING AHEAD A YEAR FROM NOW. you wont be the same person, neither will be girl A, or girl B. and most likely by then there will be a girl C-F considering how quickly you fall (which isnt necessarily a bad thing, just keep em flippin)
thats just my cent
