I have done a good bit of research on this and asked 3 psychologists who all said the same thing.
If they had to choose between living with someone who has abusive tendencies or else dealing with parental separation and all the stress that goes with that, they would choose separation.
That being said, I know what you mean about the upheaval and stress. Since I’ve told my husband about leaving, it had been painful.
I even told him I would give it another shot but secretly have kept planning to leave. I couldn’t pretend for longer than (detail removed by Moderator) weeks but the (detail removed by Moderator) weeks were nice.
