Please help

My boyfriends best friends don’t like me. I don’t know why everything was fine when we all first met. But recently they unfollowed me on social media. It’s not that noticeable that they don’t like me in person bec they’ll be fake nice I mean I feel like they just do it bec they’re all housemates and we run into eachother a lot so they have to be amicable but you can tell itsfake nice and they will try as little as possible to converse with me or even be in the same room. What do I do. My boyfriend seems obvious to it all I don’t wanna start anything by bringing it up. But he told me once how important it is that his best friends like the person that he’s dating. So I’m getting worried. I just want them to like me and I don’t see why they wouldn’t I haven’t even spent enough time with them for them to be acting like this towards me.
