I can put up with everything BUT A LIE!!!

I was in the JCR with a couple of people 2 hours ago. I saw him, or I think it was him, at the end of the room. He was with some girl. Looked at me a few times, but since we decided not to know each other in public, i tried to avoid his look, and he did the same. SO so far so good. I did not care. Would ask who she is of course, just cause I am always curious like that.
But, then they went on one of the couches, and he was lying down, trying to sleep or whatever. And that girl was leaning over him.
I know he has a test tonight, so I am not gonna try to contact him unless he comes on. But I definately will find out if that was him. And if he does not have a good explanation, I am gonna kick him out. I was looking for a reason, and what better reason than that.
And, I know you may think I son;t have the right to ask for anything, but we made a deal that we will tell each other about other people. If that was him, he did not keep the deal. So that would be a game over.
I hate lies.
