So i met this girl on Tinder, were supposed to be meeting up Saturday for a date. However she was straight up with me and told me she has a date for drinks tonight with a guy.

I kept frame and told her to have fun. I think she could sense that I didnt care because she kept telling me how its probably not gonna end well. She kept undermining this guy left and right after I told her I didn't care. (She told me this guy smokes weed every day so she was worried about that. I told her that I do too and she doesn't have a problem with me doing that)

My question is what should I do if she ends up going out tonight with this guy?

UPDATE: told her to ditch the other guy tonight and see me, she obliged
