How to deal with boyfriends friends?

My boyfriend has a group of friends that he used to live with before moving in with me. But one of the friends at his previous addres happens to be a jealous ex. Now because shes mates with the rest of them she spreads poison words about me, now none of them like me, anmd hardly no me. This os probably the hardest most awkward position i have been in with a guy. So, the story goes he lives with me we love each other dearly, but every time he wanta to go out as a couple to see his friends i hesitate on goin because i feel negative energy off everyone, ofcourse. I hate feeling awkward. Especially wen i no noone wants me there, but my bf insists that its only his x saying crap about me not everyone. And that i should just chill n let is pass. But every time we go out its crap. Now its one of the girls bdays today and he sed he needs to go to see her. Thats me being a little jealous i no, but the fact that he still talks to them after all the spiteful things they say baffles me? wat2do???How to deal with boyfriends friends?
Your guy, your rules. dont care what they think. Go to the birthday. By the way, his ex still loves him. Shes jealous of you. Because you got more looks and are better in bed. Blow his friends off, and tell your boyfriend you hate the feeling around his friends. And that he needs to step up for you. Take charge! Us women now have control over men. Let his ex be jealous. Let her dream of what she could have but cant. But confront your boyfriend.How to deal with boyfriends friends?
