I liked the curb stomping idea, I think that any time someone is curb stomped, no matter how gruesome or horrible it is, no matter if they deserved it or not, that a little bit of awesome is released at the moment of impact.

Its a scientific theory of mine.

But seriously, I would watch it there. The fact that she told him what you told her, means that things might not be as tight as you might have thought. Doesnt mean she hates you, but even so... a good girlfriend can be a good girlfriend and not tell their bf what everyone says to them. Especially telling the person you warned them about being dangerous about it.

Gotta make sure to play it cool, or else you may find yourself having just fought some dick, and lost the girl you were after.

No amount of advice from any of us is going to be all that great once you are there in the moment. The only thing that matters then is you, and what you feel is best to do. Both with the girl, and with the dick. You never know what is going to happen with either, so just be prepared for anything.
