How serious was your relationship??

i was with the same guy all throughout high school through my first yr away at college.. soo 5 yrs..but i can tell u oi was soo stupid because i still here to the day all the gilrs he cheated on me with..and when he wasnt cheating on my he was treating me like shit.. i was a dumb little girl at the time who thought there was no one else out there for me..... it was just a waste of 5 yrs but u learn from your mistakes. i really get to know the guy before anything.. im not picky with looks or anything but i def get to know about the ways they treated girls in the past and how dedicated they r to being serious.. cause now im 22 going on 23 and im not into just messing around with any guy anymore i want to get on with my life...
