You still continue your friendship and its pretty clear that he still has feelings towards you, especially when he makes a move on you. You, knowing you don't want to be in a relationship with him then reciprocate his advances. WHYYYYYYYYYYY...
Let this poor guy off your hook would you. Don't just keep him around because you like the attention, you have already ruined his friendship and now probably his current relationship. I'm not condoning his actions for making the move or cheating, however theres no way in hell you ever should have reciprocated knowing you don't want anything to do with him.
So why is not wanting any contact with you?.. because you have kept on your hook giving him hope and he's realized hes much better off with you out of the picture so he can get his head together.
