A jerk is when ur BF tells u he loves u more than any 1 else then lies 2 u and goes behind ur back and tells another girl the same thing...and when he cheats on u when ur not there and holds ur best friends hand...and tries to keep it a SECRET!! Well i know what a jerk is because my BF IS 1 !!! If ur BF is a jerk then dump him always remember that if he cheats on u then it shows that ur 2 good for him and that u deserve MORE...Don't except LESS when u can have MORE!!!
