I remember he gave your "unreasonable behavior" or some such as grounds for the D, also tried to screw you over financially somehow. It was all very low.
You will be so much better off without him if this is what he's going to be like, even with the financial difficulties D will bring. I am glad you are starting to feel at peace with it.
It has to hurt your Ds that your H always gives your S preferential treatment.
