A bit of context first. I've been with this chick for a few months now and everything's great. I've holded frame and gamed her very well thus far. I'm not giving in her shit tests, I don't put her on a pedestal, I'm not giving her unnecessary attention. At first she was confused by the fact that I didn't chase her like a beta orbiter and didn't validate her. But this made me stand out from all her other exes.

Today she was supposed to becoming over to my place but she couldn't because of her work. We talked on the phone, she was upset about a lot of stuff, got into an argument with her boss etc. Anyway she asked if we can reschedule for tomorrow, though I had already plans for tomorrow to hang out at a friends place who is throwing a party. So I said I couldn't and explained to her why which made her upset. The tone of her voice changed completely and she hung up.

A few Hours after our phone call, my friend called me and turns out he will postpone the party. So I texted my LTR and told her the news and that we can hangout after all.

Her reply was: "Sucks... goodnight."

I'm pretty perplexed by it. Am I supposed to give her what she wants and communicate with her tomorrow to clarify weather she will come or not? Fuck no. I'm not gonna beg her or "chase" her so I can fuck her. This will instantly feed her ego, validate and enable her behaviour even more.

What's my course of action here? Thanks in advance.
