breakups suck

my boyfriend, father of my deceased children too has cheated on me after one year and 2 months the night in Kansas City before basic with one of his female battle buddies in basic training. He wants to remain friends but i dont even want him writing, calling or visiting me after training is done. he still know my hormones were in a tizzy and he thought the breakup would stay in the back of my head for awhile since i got others things to worry about. Whats a good way to get over him fast?
