My friend is talking sh!t about me to my friends . What should I do ?

[Alex]

So here is what happened . We know each other for like 2-3 year. When we met there was also this girl witch he used to date , but they broke up I think after we met , but we were still friends . However the girl start to give more attention to me than him and after a while he started b!tching that we are talking behind his back and one day he just pissed me off and I told him to stopbeing such a b!tch and act a little bit like a man .

After I told him that he started ignoring me and I think that he was talking sh!t about me behind my back because all the friends who I had around me and him (hope you know what I mean) started also ignoring me .

I'm really pissed off because those were good friends and now they hate me for no reason . He is too pathetic to beat his a$$ . Talking sh!t about him will be stupid because only people he is friend with are those that he turned against me and also thats a bit pathetic . So if any of you were in my situation what would you do to get revenge on that f*cker and perhaps get his friends back or atleast let them know the true .
