It has been two years since I broke up with my ex-girlfriend. I send her messages occasionally. Today, I sent her an expression. She replied that lying on the list is not cheating, is it?

It's been two years since we broke up, and you still send her a message. When she replies to you, she means not to disturb her. In this case, she either has a boyfriend or doesn't want to chat with you. No matter what happens, she just doesn't want to continue with you, and she may not even want to be friends.
