Any chance I can get something with him?

Once I saw him, I said goodbye to with a spanking. A week later he fb me and asked my number, then I asked to hang out...we just talked, didnt tried to kiss me. Took me back homee, barely said bye. A bout a month ago
sunday a celebration, everybody get drunk and we met and we kissed, he confessed that he thought I was not interested. He also he remembered he started liking me when we met on the street and went to eat togetter (4 years ago), wow he remembered, I told him I had always liked him ( drunk chat.... )
he invited me over, I told him no and asked him out next saturday, he said ok.So far he has not made contact with me.I dont know if he is just shy, expect me to chase him, not interested or what.
They say lil johnny is a bit shy and somewhat square, sometimes a little silly, do not know how to act.
WHAT do I do? should I write? How long should I wait? What if he doesn't write? WHat are my chances with him?

I think your chances are good :) Give him a call or text and see how it goes from there. Good luck!
