Well I've been going out with this guy for like 10 months and he's 17 and in 10 th grade , & he messed up 3 times already talking to other girls behind my back ...but anyways Well my boyfriend dosent like any of my friend . Well I have this friend who I call my "bro" , he's like a brother to me . Well my boyfriend dosent like him , my boyfriend says I talk to bro more than I talk to him . My bf threat him saying for him to leave me alone . Plus my boyfriend says I have to delete my friend on facebook if not he's gonna stop talking to me . I also have this other friend who I'm really close to . My boyfriend dosent like him either , my boyfriend threated him to beat him up . He also says I need to delete. Plus he calls me a "dumbass" and say I'm "his bitch" and he just told me he calls other girls "sexy" . I just got off the phone with him and he said "your lucky I'm not one of those guys that hit they girlfriend , I would been fcked you up"
