He's not staring at you and counting wrinkles or thinking you're ugly. As a guy, I don't think that's why he'd stare. I'd guess either, "wow, she looks stunning!" (And that's a plus, because, duh. Or he's thinking "man, she looks tired/sad/exhausted." In which case he's actually caring about you.
Sorry for long distance mind reading, but I don't see that a guy staring is a bad thing. Especially not if you were just being flirted on earlier that day.
Stick with it! No R talk. Be awesome!
