I don't see why anyone is trying to convince anyone not to go back. We do not have to live with the consequences of their choices which in turn is how they cannot possibly understand how many of us feel who are in fact living with the consequences of our own choices (however they may have played out).
Let them go back. It's their life. There are those out there comfortable enough being controlled. Let them be rather than waste time trying to save them when they obviously don't want or need to be saved. Rescuing a lost puppy is more noble than trying to "save" or rationalize with someone whose only goal is to incite trouble.
Again...go back and have fun. Good luck.
