Drunk 21st and met a guy!

Hey yall, so last night was my 21st birthday and me and a few people went out to celebrate. Well, towards the end of the night I met a guy thanks to my sister chatting it up at the bar, and we danced and talked, he even gave me his number we texted and called last night after I left, soooooo, what should I do? Should I wait for him to text me or should I let it go?
