What do you do when your friends hang out with someone you dislike?

Well there was this guy we used to be friends...he was funny and it seemed like every time he would want advice I would give it to him... And he would ignore my advice becuz he liked drama...he thought he was bad and would make fun of me and I got tired and I was like I'm just not gonna speak to u any more...so back to ur question...maybe talk with your friends? I'm pretty sure u have but do they understand? U need to try to convince them to have times where only u and them meet up and tell them that u dnt feel comfotable with this guy...and yes he may do good stuff like buy them something and not u but dnt let that upset u..just pretend that he's not there and only talk to the friends that u like..don't walk buy his side ....but I kno u dnt wanna here ignore him...but yea like I said try to see if u can have certain days just with them....do ur friends know that he is 2faced? Have a conversation with him...i'm pretty sure that they will realize that he's a 2 face becuz it happened with me...I hope I helped a little Kendal
