Hi Pal - Got told on the 18th March, started getting more positive roughly 5 months later. In the interim I have been living 35 miles away. Seeing each other maximum 5 times a month, no kids. Total blackout really. Sometimes 6 days without communication. On reflection letting go of the idea that her coming back would 'save me' was a very important and equally painful experience. But like anything in life, over time the pain dulls bit by bit until it doesn't sting anymore.
I know its different for you because you have kids, so I don't claim to know or understand your situation, and I don't claim that if you follow these words it will always be sunshine and rainbows in the end.. however the detachment aspect in itself really is a new lease of life that will more than likely open new avenues for you no matter how things end up with your W.
