Do you think he really wanted the kiss, or was he simply being an amazing friend?

I personally think it`s sweet that the guy gave you the choice, but then again, he is your best friend. Either way, it shows that he considers your feelings, which is always a good thing. I don`t know much about this guy so I can`t really say what "motive" he had for this game, so it`s up to you to figure out whether or not there could be a future relationship in the works for you guys. Good luck!
