<human>: Can you give me a shortened version of the text?

I need to tell a friend of mine that his touching and persistence made me very uncomfortable when we were on a tester date, even though I told him several times being touched in public without my permission (he touched under my bra) made me very uncomfortable.

We had planned on going to prom together, which is coming up pretty soon, and because of weird scheduling I won't see him in person to tell him I no longer want to go with him and that I don't have feelings for him for another week. Is sending him an email an acceptable alternative in this situation?
<bot>: A date went poorly (although he didn't think so) and I want to call off prom with him so that I can relax and enjoy myself. Is text an unacceptable way of telling him this?
