Just graduated college where we were an LTR. Now we're in different cities. I told her that we were no strings attached, and that when we see each other, we would have fun.

Now that I arrive, and am in her bed making out, she goes "You're going to hate me for this. But there's someone else. We haven't done anything [trickle truth I'm sure], but this weekend I just want to be friends. Is that ok?"

I say "No." and awkward smirks are exchanged. All sexual escalation stops as I'm just dumbfounded.

We just had dinner and are making plans for the night. Kino is at an unprecedented low. The thing is, I'm supposed to be staying here all weekend. I'm quickly looking for other friend's places I could stay with in NYC.

Please give me advice. I'm in an essentially foreign city staying with a now broken plate. I know I've made mistakes. Feel free to explain them so that I may grow.

Do I try and escalate for tonight, and if it doesn't work out stay with someone else? I know you can't negotiate desire, so an ultimatum may not be the best move, but it might work.

Immediate actionable advice preferred. Thanks!
