So you were out with a friend, took a liking for a guy, but then it turned into him liking your friend, you and this friend went to his place drinking wine, she fell asleep so you left her there with the guy, and now you want to know if there will be something between you and this guy
He DID like you but only for very briefly, when moon was trine mars in capricorn both at 29 degrees, mars exalts moon. It also didn't help with mars being conjunct Alcyone fixed star, its the seven weeping sisters star which is associated with jealousy and envy, competition, sadness. This is why you left his flat, you would have been feeling all these emotions.
I mean if i went out with my friend and started talking to a guy, my friend full well knowing i like him, there is no way my friend would be entertaining him if he suddenly then took interest in her. So this friend of yours doesn't seem like a great friend to me.
Saturn is your friend, your in her fall. Mercury wants saturn, but it doesn't look like she reciprocates. Your next, but at the same time you go retrograde so you'll change your mind about him.
ETA: You shouldn't have sent him a facebook request.
