I don't think the two people in question are actually going out. They're very much drawn together, and they certianly have feelings for each other. They've talked about getting together, but both of them are worried about what other people will say, etc.
I'm really just wanting to learn more about these kinds of situations, as I'm really good friends with one of the involved parties, and I feel that the more I know about this sort of thing, the better a friend I can be.
You're not fooling anyone, now get in there and bone it til it's dry!
