So your friend kissed you and then announced to another friend he has no feelings for you. Well, that could be a number of things. First, he might be trying to hit on your friend. Second, maybe he didn't like the kissing, so decided you weren't for him. Generally though, this seems like kind of a weird reaction. Honestly, the best thing you can do is to tell your friend he was a bad kisser and that you're happy he doesn't have feelings for you so you can just remain friends. This will make you seem like more of a challenge to him. Ignore him. This will be the thing most likely to get him wondering about you.
