Men (or certain most men anyway) tend to take what's on offer. If your friend was going round snogging every other bloke in the club, it doesn't take much of a leap to see that she probably would have made the moves on this guy as well.
Now at that point, and forgive me if this isnt what happened, nothing had gone on between you - he'd made it clear he was interested, you say you'd got on well, but you'd resisted his attempts to kiss you and gone home. Quite possible, and assuming he's a decent-ish type, he may have thought along the lines that he liked you, but wasn't sure anything would come of it, hence no reason to pass up your friend if she made it clear she was interested. At that point he didn't know if he'd see you again. So I don't think he was necessarily wrong in doing what he did.
I also don't think there was any way he could then have mentioned it to you the next day. You would have thought he was a complete sleaze (admittedly he might be...) and wanted nothing to do with him. So again, not wrong in keeping quiet.
Where he did go wrong, ime, was denying that Friday happened. I don't like the sort of man who says people are lying to cause trouble. It's rarely true. I suspect he was pissed off at being caught out, and that showed in his reaction. Getting angry about it suggests annoyance at being found out. I expect he is, in view of his financial position, rather used to people dancing to his tune.
I'm not sure about him. It's the reaction rather than the action, iyswim.
As to the friend, did she know what was going on with you and him? If so, she's not much of a friend if she made a move immediately after you left (and assuming she would have known you were interested). I have to say also that my days of snogging several 10 men in one night in a club were in my early 20s, assuming you're not that age, I'm not sure I'd be pursuing that friendship much further.
Ultimately neither of them have covered themselves in glory. I think I would chalk it up to bad experience. You are not cheap, and don't let yourself think that way, whats that quote about no-one can make you feel bad about yourself without your consent? Or something like that.
