19 F with barely any friends

I am a 19 year old female who a lot of people like and talk highly about, but I have never had a friend group. I always feel like an outsider. I have since I was a little. Everyone shuns me and makes me feel strange and too much. I do have an outgoing personality but I have trained myself over the years to not be too much, ask questions and not talk about myself. I know for a fact I’m really kind, and I’m not bad looking either. I have a boyfriend who loves me to death and insists I’m not weird. Any similar experiences?
