don't text her.
if she texts you; great, wait a little bit to respond back and don't turn it into a full fledge text convo - keep it short. dont ask her out for the next date via text. call her tomorrow and tell her you're busy friday but you could hang out on saturday and invite her over on sat. (obviously use information you have to better judge her available days.. if she goes out with her girls every saturday or if she's a huge weekend warrior, etc., then invite her to hang out sometime next week).
if she doesn't text you at all, again, don't text her.. and wait until tmrw to call. Texting is kind of risky for "after first-date" scenarios. Technically, if a girl is into you, it doesn't matter - but if she is on the fence (for whatever reason, could have nothing to do with you.. say she is freshly broken up or something), it's easier to be more accepting and engaging over the phone.
whatever you do, avoid being over-eager towards seeing her again. you didn't really give any details so it's hard to judge the situation, but let us know what happens.
did you get anywhere physically?
