Boyfriend's friends are jerks?

my boyfriend and I have been together for over two and a half years. I've been nothing but nice to his friends, and yet they seem to hate me. it really irritates me that they're so ignorant to me and I really have no idea why. I feel like it's putting a damper on our relationship because it upsets me that his friends are jerks. I'm a really nice person and never have done anything to upset them. can someone give me advice on this..
