Haven't had any problems opening and getting numbers, which I thought would be the hard part. After the fact when I try to follow up to make plans I've been consistently getting flaked out on so obviously I'm doing it wrong.

I've made a conscious effort not to come off as needy/desperate by waiting usually a day or two to start texting, and I've been delaying my responses when they text back. Usually I'm very direct by starting off with a short ice breaker (how was your weekend, etc.) and then asking when she wants to meet for sushi or whatever the agreed upon plans were when I got her number in the first place. Is it possible I'm being too direct? Not really sure what happens between when I get her number and when we start texting, but I feel like I'm either trying to hard or not enough and I can't determine which.
