Hmmm, very interesting nblost. Even though my H is still in the A right now, I find myself with a little case of apathy too.
Because he is not the person I remember or would want to be with right now because of his behavior, i.e. immature kid, not appealing.
I don't think it's unusual as you are trying to protect your heart and feelings. H would need a lot of work before I would consider being together again. Too many things we both need to work on as a couple.
Maybe a vet will post with some better insight. I am glad you are at a better place - sounds wonderful.
