I think I understand what you are saying.
Are you asking if there is a way you can hide a thread on your screen that you don't want to see?
If so, I don't know of a way to do that.
Also, sometimes people treat others poorly to make themselves feel better about their life.
When someone treats you poorly, just keep in mind, that person is hurting and doesn't have the capacity to understand how to work through their feelings, so they lash out.
It says everything about them, and nothing about you.
