Was messaging a girl I met at a party, high sexual tension. Then I crossed the line a bit, which bothered her and killed tension. Interest was very high so it's salvageable, but how to bring back tension after fuckup?

Not sure on what approach to use. Anything perceived as weak will ruin it, but can't make it too strong as I expect she'll need a cooling off period. I don't want to re-schedule our date until I have re-gained some of the vibe from before.

Ed: We had a date booked, were both very looking forward to it, I killed the mood so she cancelled, she is now acting forgiving, I want to schedule a new date but only after the vibe is back at least somewhat (otherwise it will feel lame compared to the initial expectation)
Ed 2: I haven't been clear enough - IMMEDIATELY AFTER a fuckup has been forgiven, where is the best place to take the conversation without looking like I'm scared that I may offend her again
