I am so, so sorry you are at this place. It hurts so badly.
I really don't think this is the end for your R with your H. For a start you have the children and he has responsibilities towards them and you. You threw him out. He didn't walk of his own volition - I think that can speak volumes.
You sound as though you are holding it together fantastically and keeping your self worth intact at the same time - good for you. This will show him he needs to make a choice - you are helping to clarify matters for him. Throwing a S out does not have to mean the end by any means. You are still in the very early days of all this.
Tell you what, I would be proud if you were my mum!!!(or daughter, or sister).
