I (23M) have a girlfriend (24F), that's the most loving and caring person in the world, we began dating last year at the beginning of our college year, I'm not going to say which for privacy reasons. About 2 months into our relationship we kind of got into the messing around with each other business (not sex). About a year later we eventually had it .We were both virgins so you can somewhat assume that after that we had it like rabbits. Fast forward about 6 months later coming up on our 3 year anniversary and she hasn't really kissed me anymore, she won't rely hold my hand, and when I try to joke around or initiate something she tells me not now or will give me a serious look. I have began to notice that she's been hanging out with her friends alot more, and those friends don't take too kindly to me. They speak very bad about me, and often question her as to why she is still with me and what she sees in me, earlier this week I asked her if she had plans friday and she said she was going to watch a movie with one of her friends and a guy that we knew. I got upset over this because she normally would tell me things like this, I confronted her and asked if she liked this guy and she said no, she has swore up and down, but I have a feeling her friends and possibly this guy are playing into why she doesn't talk to me or hangout with me as much. I'm starting to lose feelings because she feels disconnected and I miss the passion we used to have for each other. AITAH?

Update: I sat her down and talked to her, I asked her why she has grown so close to this guy and her friends, she told me the reason she got close to him was because apparently she and her friend had set him up with a girl and they had recently broke up, I asked her if she found him attractive, she said no, i asked her a series of other questions all of which she said no to and I made her swear on all her answers. I asked her if she thought he was better than me, and she gave me a cold, hard no followed by a very serious look. She asked the reason I was asking her these questions for, I told her I had seen that she had chosen him and other people for the ice bucket challenge. The last thing she said was that she was feeling sick, so I left and she hasn't replied to any of my text. Another update soon.
