Is it normal that my friends get mad that i’m not always around?

Ok so boom, I started college last semester made a wonderful group of female friends. Never have I hung out with a group of girls before college so it’s all so new to me however I do enjoy their company. This semester I’ve developed the case of a feelings for this boy who just happens to like me back. In effort to get to know him I am usually always in his room we sit talk and eat just like best friends, I would even bring him around my group of friends and they have all met and had at least small talk with him. Things are getting heavy between us because I’ve been sleeping in his room (innocently, sorta) and haven’t slept in my room for about two weeks, I still would come hang with my friends but they started to treat me different and I didn’t understand so I started to talk to him about it and ended up talking to him a lot more often. I decided to confront my friends and ask them what’s going on and they are mad at me because they feel like I just stopped hanging out with them for a guy. now as a girl we all know at some points we may put our friends on the back burner to get with someone we really like but I never put him before them when they needed me around. My roommate is the one that’s angry the most because I don’t sleep in the room and they think that it’s stupid I’m spending so much time with a guy I’m not dating (yet). I feel like I should do what makes me happy which is sleeping in his room at night and hanging with my friends during the day when they want me too, but they started to include me out of things which made me feel like they no longer wanted to talk. We had a big fuss over it and I’m trying to make it where he can come and we all hang out together which I tried today but it felt like they didn’t really want him around almost as if they don’t like him although they hardly know each other. Am I wrong? Should I hang out with my friends and drop him? Should I try and balance between the two? Or are my friends wrong? Someone told me they felt my friends weren’t being supportive of the fact that I like this guy, which I mentioned to them and they said they are supportive they just don’t like the fact that I’m with him all the time (which isn’t true).
