I tried asking him out and I think I flopped.

This guy I really like and I have been flirting back and forth for weeks but we're both super shy. Tonight was my 21st birthday and we were talking about wine. He asked me "red or white?" I said red, and he said he prefers white. I told him I've never really had white wine before, and perhaps he should introduce me to some sometime. He just said "I rarely drink. I'm a light weight." I was a little devastated by this nonchalant and seemingly uninterested response so I just said "me too" and moved on. I know he likes me. After all this flirting he has to. Maybe he just didn't pick up on the fact that I wasn't just taking about wine, I was making an attempt to ask him out. My friend says guys are dense like that sometimes. 🤷‍♀️ I'm scared to try and ask him out again at a better time in a more obvious way.
