I think that is a good thing to say. Don't add anymore to it than what you wrote here. I like that you get to say your peace about the D for the last time while at the same time showing your unconditional love for husband as his wife.
BTW, I am having some down moments as well. Yesterday was not good. Today seems better. Tomorrow will be better :-)
