this isn't nonsence in fact it makes alot of sense. we have our pasts to help us in the present deciding who to trust when to trust and when not to trust. your girlfriend must have been just playing the field or was just not mature enough to see how much she meant to you. she was younger, and 2 years doesn't sound like alot but in high school it is. girls just wanna have fun as cindy lauper sings and thats what happens sometimes, it is fun, i'm ashamed to admit how i played the field. i hurt some guys i know, but i figured i was not going to be with one person because i was having so much fun flirting. also at that age it seemed scarry to devote myself to one guy. good luck
