So I invited this girl to a Korean restaurant a week ago, we scheduled to date on march 17, but suddenly yesterday she asked me if she can bring a friend to our date.

Honestly that just killed the vibe to me.

I just answered: "well, I invited you, but I guess yeah thats ok"

but tbh, I think I will cancel that date.

What kind of answer/attitude do you guys think its the best in this situation?
