What would you do

What would you do if your one of your bestfriends breaks up with your boyfriends twin brother and no she doesn't even talk to you? I literally only have like one friend now and it's my boyfriends sister. She broke up with him yet she makes it look like she's sad and like she's the victim and everyone is being so sympathetic to her? I told her straight up how it is and she just doesn't want anything to do with it. Im kinda happy that they're not together anymore bc she was a real both to him and he's legit the sweetest guy ever but I feel bad because being with her mad him stop the drinking and partying and drug use. And now that they're not together he snaochats me while he's drunk askin me to get fucked up with him when I can't do that stuff considering my boyfriend doesn't like me doing it without him around. I honestly don't know how to feel with this and all my family problems and shit going on. Graduations almost here and im worrying about way too much stuff...
