Your absolutely right when you say it's the toughest thing you've ever done in your life. I thought I had been through hell in my life until my sitch started, then I found the true meaning of it.
Sounds a lot like my sitch too until my Wife one day quite with the sex too. That was 25 months ago, ouch!!!
I started DB ing around 11/05 and have come a long way. Hard to tell where we are sometimes the progress has been so slow but progress it has been.
