My Boyfriends friends don’t really like me

So its pretty obvious in the title so my boyfriend’s friends don’t like me and idk why they said he could better than me and that I’m ugly but they haven’t even hung out with me or anything so I don’t see how they could say that I mean I normally don’t care I mean I still kinda don’t but these are his friends and I want them to like me because they are all a big part of his life do you gorgeous ladies have any advice we have only been going out for like 3 weeks

UPDATE

sorry I forgot to say he told me this cause I asked what his friends thought of me cause I only met a couple of them
