Sorry you're here. It's a hard place to be but you can get some great advice and support on these boards.
Have you read DR? If not, get a copy from Amazon (I don't think it's in the UK shops). Back off away from your W. Let her have some time to think and calm down. Limit contact to only issues related to your D.
It sounds like W was unhappy about some things in your M before she left. What were they? Are there things you can do to change any behaviours she was unhappy about?
Although there are no guarantees, there are lots of success stories around- in Newcomers and the MLC forum. They're a great source of inspiration and evidence for how DBing can work.

Walk on, walk on, with hope in your heart. And you'll never walk alone.
