My friend (let's call her C) was basically one of my first friends in college, and she's helped me through a lot of tough shit (depression, anxiety, losing a family member, losing a friend). I've known her since sophomore year, and now we're both seniors. I'm graduating in 2.5 months, but she's staying for a 5th year. Most of my friends are juniors or staying for a 5th year, so it's going to be really tough for me to leave my friends behind. My college friends are like my family.    I've also helped C through a nasty breakup with one of her previous girlfriends. Because of this, I was happy for her when she got her new girlfriend last year, but now I think things have gotten weird.    She literally spends all her time with her girlfriend. Like always. Even though C lives with just one other dude, her girlfriend is practically her third roommate, and I know this pisses off C's actual roommate. C's girlfriend doesn't go to college and just lives in the same town we go to school in.    C has just gradually stopped talking to me. She even killed our ~600 day snapchat streak a few months ago for practically no reason. Sometimes she'll randomly send me a meme or two on Facebook and I'll try to start a conversation with her, but 95% of the time the conversation ends with her leaving me on read.    Sometimes, I'll see C's other friends around on campus and they'll ask me if I've ever heard from C, because they haven't. Because of this I know this isn't something C's just doing to me, but she's doing this to all her friends.    I'm happy that C is happy in her relationship, but I'm hurt that she's practically cut off myself and all of her other friends. Since I'm graduating in a few months, I want to spend as much time with all of my friends as possible before I leave campus. I haven't seen her in months, and I'm worried that if she doesn't get her shit together, I may not see her again before I graduate    **Thanks for reading.
