What Would You Do?

I need help in what to do. Me and my boyfriend have been together for almost a month, we have been friends for more than a year. We are super happy together and have a healthy open relationship. Except there’s one thing that irritates my life. One of his closest friends. I am not one to pick and choose who he associates with at all I find that’s not my say. But with this friend it’s different. Me and her were friends before I realized how toxic she is. Constantly talks shit about all her so called friends, backstabs people, is fake to get her way. I dont hate anyone at all, but I do hate her. She’s absolutely awful, homophobic, hypocritical, disgusting human being. Yet since shes so good at being an actress, she has people fooled. My question is, do I mention this to him? How can I possibly bring this up that him being friends with someone so toxic makes me uncomfortable? She’s dated every guy I have dated in the past. I can only think once she finds out I’m dating him, she will ruin my relationship. I need help I have no clue what to do. I don’t want to be that girlfriend who interferes with his friends or what he does, but I can’t stand the fact that if it’s not me he’s textinf and laughing with, out of all people its her. Help please.
