People in this generation are after instant gratification. If they don’t feel an instant spark or connection, they will move on. It takes years of maturity and experience to realize that connections are built over time and effort. What matters early on is compatibility not chemistry. However, people chase chemistry since that gives the dopamine rush. It’s basically the high school crush feeling that causes the heart to race and then anxiety. That’s what they want.
The reason people do this is simple–it’s boring without chemistry even if you have perfect compatibility. You do need chemistry and that’s where humor and banter comes. However, you also need patience to develop that chemistry.
Next time they tell you that they don’t feel a connection… Do yourself a favor and thank them. Then date the people who actually are past that.
