<human>: Can you condense the text into three sentences or less?

I'm going camping with a bunch of friends for a few days to celebrate graduating. I [m18] have a friend [f17] who's also going. I've known her well for a few months and we've had good chemistry, and I've not asked her out simply because I don't think I know her that well, and am in a bad place personally. But, that won't stand in the way of us hooking up while camping, because - well - I'm sure you understand how it is.

The thing is, one of my guy friends has been pining over the same girl for a while; they've got a bit of history. Stuff like, they've hung out, but never been on a real 'date', and she's been really wishy-washy about the whole ordeal; which leads me to believe that she's not that interested in him. Despite those discrepancies, he's still thinking of making a move. I think everyone who's going knows his intentions (the girl included), but my friend doesn't know that I too am attracted to her.

So, what I'm inquiring about is if he gets turned down or doesn't make a move, but I do hook up with her; is that scummy on my part? I figure that it's not really his business what I do if he gets rejected, but I don't want to make him feel like shit. I've decided against telling anyone that I'm attracted to her, because nothing has really come of that attraction, and it would be especially sappy if my friend ends up with her.
<bot>: Might hook up with a girl while camping, but friend also likes her, I might get lucky instead of him, but don't want to make him feel bad because of it. What do?
