I talked with a friend who’s significant other ghosted the relationship. They could not understand why the person was not up front and honest with them. I explained it like this:

Breaking up with someone is like hitting another car in a parking lot. If you accept the responsibility, then you have to give someone bad news. They might flip out on you. Then it will get complicated dealing with insurance companies, payment, and your premiums go up. If you drive away, you can pretend it didn’t happen.
