Met a girl last week on a class I gave. Literally had no direct conversation with her, but thought she was hot and friended her on Fb. Texted her through Fb chat a few days later, got her number. Texted with her Sunday afternoon, conversation got nowhere so I just stopped replying.

I know texting is awful to build rapport, so I want to ask her out. However I was wondering if there was any obstacle due to the fact that the only time we met in person we had no real direct contact (I gave a review to freshmen before a test they had). I might have a chance to see her this week in an event my school is holding, should I wait to catch her up in person again before I do the move?
