NO!

Fuck no, going behind my back like that. I said I would do anything! I would watch him with other women if he asked!

Carrie was torn by your apparent betrayal. A small voice in the back of her mind tried to convince her that it was a trick, that Troy was a dick, that you would never do such a thing. That voice was drowned out by how caring Troy had been. He didn't try to take advantage of her in her emotional distress. He could have, she knew: a touch to her lower back, a goodnight kiss on the cheek, both lingering a bit more than what polite etiquette allowed. A **** fuck would have been justified, right? Why didn't he make a move? Then it hit her: you had been the liar. Troy had seen through your bullshit in college - that's why you two didn't get along.

(Note- I don't think I write the 'pissed-off' female perspective well. I'd be happy if someone took over this direction of the story or I'll take suggestions.)
