<human>: Could you distill the essence of the text into 1-3 sentences?

Background: We're going to prom together, so I figured we should hangout before then and test the waters. We've known each other distantly for two years, but our relationship, if you can call it that, has only been since I asked to prom last week. We both go to boarding school, so I texted her to see if she wanted to hangout. She said she was free and said she wanted to finish watching a movie that she started earlier.

Situation: When I got to her dorm she told me that she was finishing the movie with one of her friends. I tried to take it in stride so I just sat down and watched the movie with them for the next half hour. It was pretty awkward sitting there with her and another dude just watching the movie... Anyway, the end of the movie rolls by and I figure we could sit and talk, but before I say anything she gets up and says she has to go to sleep before her roommate falls asleep so that she does not wake her up.

Problem/Question:

I don't know why the other guy was there. I can't tell if she just didn't want to hang out with me one on one, or if it was just some strange coincidence. (I should mention that the other guy is a friend of mine as well, and not interested in hooking up with her)

If it was some strange coincidence, why did she run off after the movie like that?

Should I try to hang out again, or was that a sign that she would prefer to just go to prom and be done with it?

Am I dumb/oblivious?
<bot>: I went to my prom date's dorm to watch a movie and another guy was there. Not sure if that means that she wants to hangout or not...
