M22 F22 F22 what is the best way to handle this situation?

There has been a lot going on in my life recently and it really hasn’t slowed down at all. There are two parts to this and involve each other so I’m going to split this into to sections.

I have been friends with this girl for 2 years. We both started to develop feelings for each other. I asked her out at first and she rejected me but we remained close friends. Eventually after couple of weeks after that she asked me if I wanted to try and take things slow and begin a talking phase. I said yes and I thought everything was going well. Then two weeks into this we both went back home for winter break. She asked me if we could call and out of nowhere she said that she thinks we should end things but to remain friends I was fine with this I was mainly upset by the way she handled it and waited until we couldn’t talk in person to say something. I will be honest i didn’t react in the best way to it at the time and just sent her a long message just explaining how everything felt from my perspective because i was hoping that being open would make her feel comfortable to give me some insight on how she was feeling. I mainly wanted to make sure that I hadn’t done anything to make her uncomfortable because i was worried that i had since this happened out of nowhere. She said that i didn’t but we she wait to talk until we get back from break. We got back from break and we held a discussion twice and both times she said i didn’t do anything wrong she didn’t really give me too much insight just the fact that we can remain friends. During the second discussion I just apologized for the way i reacted when she first told me but she said she didn’t think u did anything wrong. I have a class with her and told her I may drop it if things didn’t go well because because i didn’t really know anyone else in the class and only took it because of her. She said she understood that. So fast forward to the first day of that class and she comes up to me and asks to sit next to me. So i thought everything was fine. Then the next day she sends me a message saying she isn’t comfortable with our friendship and isn’t up for discussing it. So now im like fuck because now it was too late to drop the class. but also I’m upset because she made it sound like I was the problem this whole time when all I ever did was try to make sure i didn’t do anything to make her uncomfortable and I thought I wasn’t because every time I asked she said I wasn’t. She also told me she has no hate or dislike towards me. But now fast forward a month and she just recently blocked or unfollowed me on everything. But it’s not because I reached out to her or anything I haven’t contacted her since she cut me off. I’m just really confused by it and part of me still wants to be friends but I kinda understand if that isn’t possible.

The second part is a development happening now. Her roommate is probably my closest friend now that she cut me off. But her roommate told me that she really likes me but understands if I don’t because she knows everything that has happened. I told her that I might have like a sliver of feelings but wasn’t really sure if a relationship would be the best thing. I kind of want to give it a chance but I have many hesitations. 1. She is best friends and roommates with the girl that cut me off. 2. Her and my roommate hate each other. 3. Because of these two things any time we are hanging out we are constantly paranoid that one of the two will walk by and see us which was already happened and it just increased our paranoia. 4. I don’t know if it would last long term because we have such different plans after we graduate. 5. I don’t fully know if my feelings are fully genuine and part of me is still sad about the previous situation. 6. She just got out of a relationship like 5 months ago then got into another relationship immediately after that only lasted like 4 weeks so that makes me nervous. 7. I don’t won’t to lose another close friend within the span of a month if things wind up not going well.

TLDR: out of nowhere I got cut off by a girl then her roommate confessed to me. Idk what to do.
