Sorry isn't good enough.
Sorry doesn't mean you will stop doing what you do.
Sorry doesn't mean that I now trust you again.
Sorry doesn't mean your actions will change in any way shape or form.
Sorry doesn't mean that our relationship can now go back to what it used to be.

Sorry means "I know I stabbed a knife in your back. It didn't occur to me that it would hurt. I'll try to remember that next time."

They never remember next time.
