How do I get my friends to stop leaving me out.

So it starts off with my 2 friends from my class talking to each other but still involving me, we talked about the party that was coming up. But as soon as the party was done, school sucked. Today I went to school while the people I hang out with just talked right in-front of me, not involving me whatsoever about all the parties their going to, how their going to have a power point night & kahoot night. And I’m literally having a party myself just to involve myself again. I feel like the reasoning might be because I told my best friend & one of the other girls how I can’t deal with my boyfriend & that I’m starting to get off him, and I never do anything about it, but also the another on of the girls already hates him without me even saying anything about him, but my best friend, seems to like him some what. I don’t want to leave my boyfriend, I go to them for comfort when me and him are having rough times, but maybe I take it too far, & they don’t like it & now have an opinion on our relationship & that’s why i’m being left out & maybe their teaching me a lesson, to break up with him & maybe they’ll start to invite me out. I also just don’t want to have to break up with my boyfriend just to be involved with my friends again, he’s really easy going, and fun to be around, but I don’t know. I don’t know how to bring it up to them, one of them is my bestest friend, but she seems to leave me out unless it’s just me and her alone. Any ideas on how to involve myself more, or to talk to them? Or even just my best friend?
