Hey, although i admire your courage of going on a date with her, maybe its not such a good idea to go with someone who you don't like that much in the first place. Maybe somehow she felt that and reacted on it (in a very bad way, i have to say). I hope you didnt let this traumatize you in any way, because the way you discribe it she is the one who is acting strangely and not you. Just try to learn from the experience and try again Btw, a bad date is better than no date at all. Being asked on a date must feel as a compliment.
