I NEED HELP!

I REALLY NEED HELP! My used to be friends think that I like EVERY GUY! I am happy with the one that I got! I love him to death! No one REALLY knows how much I love that boy! But she is like sitting there cussing me out and I wanna do something about it and I have turned my check so much! I have turned the other cheek and then turned the other one and I am tired of turning cheeks! I know that the Bible says to turn the other cheek but sometimes you cant help but not! This girl has made me and my other used to be best friend become to where we hate each other! Me and him were friend before Kindergarten! This crap is ticking me off! I really need some help! If you have any comment this and tell me! Thanks!
