As expected, her "running into him" was more like "we were texting all night and decided to meet up at 3 am, which I normally would never do because it's so late, but I was drunk".
I hate it when she downplays things like that.
Just be honest, even if it's bad, and I'll know you're at least trying to be honest with me and are committed to me.
Ok, so now I am mad at her for actively meeting up with him. We are supposed to tell each other as much as possible about dates beforehand. That can't happen with spontaneous things like this. Spontaneous coffee friendly dates are ok as long as I hear about them afterward, but this is not that kind of date.
