Hi! I've never used Reddit but I'm Really stuck on this situation for my freshman year dorm and I'd like some outside opinions!

I am 19 F, my boyfriend is 19M, and my roommate is 19F, we will call her Nes,So just as some background information Nes originally reached out to me before roommate selection for my college, we hit it off and we talked back and fourth about boundaries, wishes, etc. some major point outs was that we were both perfectly fine with friends and guys over. At the time she had a boyfriend she was with for about 1 year or so, and I told her I was totally fine with him being there as much as they want. She said the same for me. This is a 2 room one bath and a shared common space, so we have separate rooms.

Now here's where the problem comes into play. As soon as the year started I only had my boyfriend over every other day for a few hours, she broke up with her boyfriend, and from then on every single night without fail she would have guys over every night all night. So I started to have my boyfriend stay the night any time she would have a guy over because at the time I didn't know how to lock the door (it's a touch lock that you lock from the outside with your phone) so there was no knob. Keep in mind I had never met any of these guys and I was starting to feel severely unsafe. After he started staying, Nes started to obviously flirt with him, saying stuff like "black women deserve Mexican men, white women need to F*ck off!" (I'm white, my boyfriend is mixed with white and Mexican, and my roommate is black.) she had made it a point she is a "proud homewrecker", and she would also try to give him full hugs and would just walk into my room never knocking on the door, just barging in. we never do anything sexual if she is in the dorm so Luckily she didn't walk in on anything but it's still the point that she refused to respect me asking for her many many times to knock before entering. After a while of her constantly barging in, trying to hug my boyfriend and making both of us severely uncomfortable, I told her nicely to please stop touching him because it made him uncomfortable and he hated people touching him no matter how close they are to him. She then started complaining to the RA that he was "making her uncomfortable" and I had to explain to the RA about the every night different guy situation, so the RA dropped the complaint.

Please keep in mind I have brought up these issues many times with her, only for them to be ignored. I agree I shouldn't have to have a guy over, but when it's a situation of her constantly having guys she met at parties over and they can easily access my private room, having an extra person just feels a lot safer.

I feel unsafe in my own living space and I feel as if I've had to bring someone to stay just so I can sleep without fearing someone walking into my room at night. Sorry if this was all over the place I've never done this before but I just want some advice for what to do about this. Am I the asshole for having my boyfriend at my dorm every day?
