My boyfriend wants to be best friends with a girl and im scared he is going to leave me

ok my boyfriend just told me that he wants to be best friends with a girl and I dont like it because what if he leaves me and likes her ? and I dunno like im a slefish person at times like when it comes to him like I want him all to myself and I know thats bad but I cant help it and I dunno I dont want them to be friends and I dont even know her and my boyfriend will flip out if I was best friends with a guy and I know that he will make me not be friends with him any more so what do I do ?any advice for what I can tell him ?

Maybe you should go get a male bestfriend..see how it makes him feel..then when he gets upset tell him thats how you feel with him having a female bestfriend..its healthy for your boyfriend/girlfriend to be your bestfriend it makes thing a lot easyier..maybe you should tell him youde like to be his bestfriend

hey you should let him b best friends with a girl and then git your slef a guy thats a best friend build a good realashion ship with him this way if he leaves you u know you can git him back if he gose with that chick he wants to b best friends with and its normal to want him to b all to your self some times but when you start contoling who he can and can not hang with thats not rite same thing gose for him!

ok maybe he already does like this girl more than friends, why would he want to be best friends with her ?? I dont get that?? it seems like a lame excuse for something...
