I think sometmes DBing has to take a back seat. When your spouse has left you, is living with another, and trying to deny you basic legal rights to property it is necessary to state our position.
Interestingly, they do take it in, in a weird way. Not at the time, but later on they will admit the truth of our words.
Dbing can work, imo, on people who are emotionally firing on all cylinders. It is a good approach to treating others, but where people are really off beam, sometimes we have to say it as it is, just as we would to our children and friends,
You are doing well. The strength and grace of so many people on these boards is inspirational
