I'm going to cancel a date.
Why are you canceling your date?
Things are not working out between us.
I'm sorry that you're not compatible, but you already made a date and it's essentially a promise. You need to keep your end of the deal and just go through this one more time to keep them happy. You don't want to be known as that person who just ghosts a lot of people like nothing.
It's not a big deal and my life is more important. Plus, I can also find someone new to date.
Are you sure that this is true? Finding someone that you connect with can be difficult for a lot of people, and cancelling a date may ensure you don't have a new one in a while.
