Okay, OP here again.

So I'm going to text him today after work as I'm returning to the college town tomorrow morning. I think I'm going to invite him to my place and cook him dinner this weekend. If nothing screams "DUDE I LIKE YOU" it's that.

Anon, tell me whether I should pregame with one or two smirnoffs. I realize my body language is not particularly flirty, but with two drinks in me I stop clamming up so much...
