This sounds all too familiar. As I said on my thread, I find nothing encouraging about it. I am only annoyed for the both of us. I still don’t know the reason (other than checking) that my H. called last night; whatever it was, he did not say. And you are right, they could just leave a message and not call continuously.
Most of us really marry only once. First love endures, even unto our dying day. And we never really divorce.
