Bf problems

Marissa • I smoke weed everyday
So today at school (I still go to high school) when break started I was sitting with all my friends and my bf came and stood next to this girl (we will call her Jill) and Jill is my bfs childhood friend who likes my bf and he knows that and anyway I was expecting him to give me a hug or even say hi but no instead he gives her a hug and then after a while he came and sat next to me and asked me what's wrong and I said that nothing was wrong but Idk if I should just wait and get over it like I always do or talkto him about it but if I do talk to him about it what should I say??? Pls help am I just over reacting also he hugs this other girl too and he also has dated Jill two times before...
