Dates aren’t always the most pleasant meeting that two people can have. There are various factors that can make people act in a weird manner. One very important factor is the possibility that one of them is not over their ex and they keep bringing them up throughout the date. That’s bad for both parts, since the one who’s stuck in past is not helping themselves move forward and they also make the worst kind of impression they could make to the other person. My advice would be to remain calm, reveal only the basic things about yourself and be nice to your date and the people around you.
1. That’s an A class insult that you should hold until the right moment comes and you can return it.
2. Bringing up your ex will instantly ruin the atmosphere between the two people and they might never recapture it.
