Lobo,
So sorry you're going through this. I hope that it's just a small slip and she will learn from it and move on.
I hear that YOU hope that for her sake he'll pretend nothing happened and keep dating her.....but I know that if I had a similar experience on a date, it would be the last date. What a thoughtful young man, to phone you like that. It's no fun to deal with people who can't control the chemicals they put into them. (of course, he is a bartender, so maybe that doesn't matter to him)
Hoping that she will be able to absorb the lesson here, and not make it again.
Hugs,
GL
