FWB of two weeks tells me over dinner that there's a new guy that she's agreed to be FWB with and more or less asks me to define the relationship I have with her. I'll be leaving the country in a month (though I'll coming back), and having been using that as an excuse as to why I didn't want exclusivity but kept on dangling carrot with "but who knows what will happen." She had been asking whether there were other girls that I was fucking, and I maintained my "neither confirm nor deny" position.

I feel as though I've been disrespected, though she tells me she didn't want to "deceive me" by not saying anything while fucking another dude with no strings attached. It makes it worse that she rejected renting a room to fuck today since she has classes tomorrow.

Could you give me some perspective here? Do I keep on seeing her as if nothing happened? Do I demote her to a plate, and if so, how would I do that without seeming butthurt? Soft next?

PS: I withdrew some attention already and she's already sensing it, sending me texts like "Did I do something wrong today? :(" What should I say?
