Bestfriends boyfriend disrespecting me .

So we in this groupchat , and my bestfriends boyfriend starts to make fun of me you know for no reason, cause I told him to unblock her being the good friend that I am he was supposed to help me set up with somebody and then he says I’m unsending it so I said ok idc then he jus starts roasting me and my appearance, and then I’m like wait how does he even know what I look like ? And she says I sent him a meme thing so I’m like being the assertive ass bitch that I am, like why? I don’t even know how he look like, Ik there bad photos of me like on FaceTime and I’m not ugly at all but I jus find it unfair and instead of defending me or telling him to stop attacking my appearance cause I have no clue how this long neck ass nigga look like and he keeps making fun of me and I’m like ok, but she doesn’t even try to help me? We’re on ft so I hang up cause I’m agitated, like wth did I do ? Idk mane
