I don't want my boyfriend meeting my friends. Help...10 POINTS!!!............?

My two best friends. Where do I begin. They are drama, gossip, mean, snotty kind of girls. We got into a huge fight about 9 months ago and things have never been the same. I basically moved on from them and got my own life. We made up over time. And talk on occasion. Me and one of my friends are starting to talk a lot now. She wants to become close with me again. She had a baby and is getting married and asked if I would be the brides maid. I accepted. The thing is, I have changed so much since we all split up and went our separate ways. I am the complete opposite of my best friends. As messed up as this is, sometimes I feel sorry for them that they are the way they are. I love them but you need to understand how mean of girls they are. I don't gossip, I don't talk bad about anyone. I am at peace. And it's because of my boyfriend. He has changed me in the best of ways. Anyways, eventually if me and my friends get close again, they will probably want to finally meet my boyfriend. I do but I don't. How do I explain that to my friends and my boyfriend? I have a feeling my boyfriend won't like them lol. Is this wrong of me?
