Have a second date today!

Well, I'm not counting the time a friend and I met up with her and her friends at a bar. But after that I asked her to go a to group event and that went very well. I wasn't sure how it would go when my ex-girlfriend was also at the event. It seems like it should be a bad idea to introduce someone to your ex on a first date.They actually got along. My ex thinks I should date her. My date said she didn't care if I still wanted to date my ex. Not sure if I can make that happen.
