Problem

I don't know what to do. You'd think in this situation it would be cut and dry, no debate or back and forth. But that's exactly what I'm doing. 

I try to justify it with, well I don't know the whole story. And: maybe he only wants to be friends and I'm the one reading into it. And even thinking up ways that this could even possibly be ok! All those sound good to me, and I can also justify myself by saying: well I just don't know what to say so until I figure it out then I'll address it, until then I'll just go along with it. How far am I willing to go before I say something? Am I trying to just satisfy myself ? 

But its SO not ok! Right? Why can't I convince myself this is wrong??? 

I mean, I KNOW its wrong, otherwise I wouldn't be so worried about it, but why isn't the fact of HOW wrong it is stop me from wanting it? I guess wanting it and acting on that want are two totally different things. Problem is... I don't know if I'd stop myself from acting on it if I got the chance... Oh help.
