Is there anything I should avoid discussing on a first date?
On a first date, there's not many things that you should avoid discussing, except probably your e-girlfriend. It's a no win situation because you're comparing this woman who is sitting in front of you to one of your ex's, and it puts everyone in an uncomfortable situation. So without a doubt, never mention your ex on a first date. Even if she happens to bring up her ex-boyfriend, do not bring up your ex. Even if she's asking you and begging you, don't go there on a first date.
