Want to be more aggressive here (Date flake)

Context: Met on Hinge, had one facetime. On the facetime she told me she's bi and doesn't believe in monogamy. Supposed to have a date tonight but she hasn't responded to my engage txt (1 1/2 hours ago). Yea, I know she could still come through, but from my experience at this point it's highly unlikely she does. I want to say "I didn't take you for that type of girl" or something to that effect.
