<human>: Condense the text into a few key points

My future roommate (20F) and I (21M) have been hanging out a lot recently.  I've slept over at her house, in her bed, a little over a half-a-dozen times over the last two months.  We've cuddled a few times, but she says its "awkward" to do so, but is okay with "holding hands" when we sleep.

She happens to apparently have a crush on our other future (and my current) roommate (21M).  I don't know if he's interested or not though.  I've asked outright, and he says no... but I don't know if I believe him or not.

I think I'm starting to have a crush on her.  As I'm sure you can imagine, this is problematic.  She's not only going to be my roommate for two semesters, but she also has a crush on my roommate.

I don't want to play second-fiddle to anyone... I don't want to provide her with all the advantages of being her boyfriend, minus the physical intimacy and the commitment.  I feel used and don't think its fair to me.

Any advance?  I don't know what to do at this point.
<bot>: I have a thing for my future roommate, who uses me as her pseudo-boyfriend.  She has apparently has a thing for our other future (and my current) roommate.
