Guy gave me a card, I tried to act smart?

Anonymous
I work as a cashier and smoothie or tea maker in Costa Coffee. I fancied this customer who was one of our regulars, coming in often as twice or even thrice daily.
I was so into him that I would give him stuff for free, bring him his drink personally, keep his drink with me so that he wouldn't have to run around etc. I also used to stare a lot at him.
My hours were drastically reduced as compared to last month so I saw him only 1 or 2 days compared to 4 days I a week.
He gave me a really nice card writing thank you and how sweet and kind I am. He also wrote his name and if I ever feel like hanging out with him after work, I can let him know. He didn't write his number so the next day when I saw him, I asked him that when he comes in next time, he should write and give me his number.

He laughed and said sure.
I didn't have any shifts after that so didn't see him and yesterday night, I was laid off unexpectedly. They didn't fire me but said they will decide when to give me shifts. Until then, I need to wait.

Now I feel terrible. I wish he gave me his number but now I feel I should have given him mine too considering he gave me the card and the invite. Or asked him to meet up with me then we could have exchanged numbers.

What do I do? Is this a missed opportunity and did I outsmart myself?
