You seem to have a rather simplistic view of things. Technically speaking, of course, anyone can leave unless they are in prison, or destitute. That does not mean that there are not other reasons or factors that make leaving more problematic than staying for some period of time. That is the point I was trying to make. Life isn't always so simple, or so black and white as you seem to think it is.
I agree, but what I hear you saying is that you are choosing to stay. This is your call of course. People are prisoners for a great many reasons of their own choosing.
I’m in PA part-time because our grandkids are here. But of course, it isn’t NJ.
