Which would seem a better decision to make?

1) Have short-ended conversations with small bursts of passive flirting, 1-2 times a week. Given we see each other often.

2) Be straight up front with how I feel about her, no teasing or playing games. Having one conversation to air this out would be the motion.

(PS. I don't think I'd have the patience to wait to find out if she likes me enough or not)
