You're very good at 'text book' responses, but your answers suggest that you, personally, have little personal experience of estrangement and the hardships that ensue.
You appear to 'know it all' but the consensus on this thread, even from posters who are not estranged, is that you don't. As no-one, apart from 'magic virginia * Bibbity*', appears to find your comments helpful, perhaps you would consider moving over to Mumsnet and giving them the benefit of your inexperience?
Good night all. It's 11.30pm here,and we have an early start tomorrow.
