<human>: Can you give me a shortened version of the text?

Her boyfriend and her are on a break and all she seems to do is complain about his ineptitude in practically anything. Last night we were drunk and got a bit flirty, and we ended up sharing her bed. By the morning we were alarmingly closer and more touchy-feely than before and since I left hers she's been messaging me constantly all day trying to get me to go back.

The part where I feel awful is that I've been specifically mocking her as an undesirable candidate for about a year with my roommate, and even know he's continuing it and I don't want to be the one that stops him. He knows about last night but he promised to not spread it based on the sheer amount of stuff I have on him.

On top of this I feel like I'm facilitating her too much when I don't know what I want, and she said something to said roommate along the lines of "I think I'm falling for X" and it made me pretty uncomfortable to hear that from him.

And the final part that's irritating me is that her roommate is an irritating cunt so if I decide that I do want to be with her I have to deal with that attention-seeking shithead and that feels like a big deal to me.
Anyone got any advice for me? Or any other perspectives to look at this from? This has been a pretty alarming day and I feel like my brain has fried.
<bot>: Got close to a girl I didn't ever imagine I would for shallow reasons. Really don't know how to go about this with how my friends perceive her and my opinion regarding her. Also feel like I'm fucking someone else over.
