You're spot on, when I wrote that, I didn't really believe it. So basically, I have 2 options.

1) I don't respond to her emails or texts, and I don't go anywhere where she might be.

2) I don't respond to her emails or texts, and I do still go out, but ignore her and talk to other people. (I still need a social life. She is always out with my friends, so it would really mean not seeing my friends if I didn't go out.)

I prefer option 2. Obviously it's not perfect, but I'll get the chance to try it out next Saturday, and if it doesn't work, I'll resort to option 1. Does that sound reasonable? I can get over this.
