Thanks for the great replies everyone. W admits she has tried to get herself to end the affair but either can't send that text/email and go cold turkey or gets sucked back in by OM.
She is having a text-book MLC so I don't enter into her thinking as I am the cause of all her problems.
The struggle is between OM and our children who still are in total ignorance of what is going on.
It is clear I have not met her emotional needs through ignorance, of course now I know better all I need is a chance..........
