Ok calm down.

He is into you, 100%.

He asked for a kiss, and you only kissed his cheek, you did not breach consent or make him uncomfortable.

It is ok to be silly and romantic and run away because you got flustered, just rail it back a bit so that you can have and maintain grounded expectations.

If you aren't talking recently, it is most likely because YOU have stopped. Ask him if he wants to go out again, he will tell you if he doesn't.

Enjoy yourself, don't worry about how people look at you as long as you stay safe.

Good luck.
