My first marriage ended in divorce after my x committed virtually every act of betrayal I could think of except infidelity. I used to joke that he'd cheated on me w/ his bookie, his friends, his beer, his sports, but never w/ a woman. I found out after the divorce and from a couple of my very own brothers that he'd been unfaithful.
So then I felt betrayed all over again and not just by my ex, but by my brothers. I would want to know if my husband was running around for a myriad of reasons, not the least of which is the possibility of disease....yes even "nice" people spread disease!!!! I'd hate to be the teller of that tale, but having been there, I'd be grateful to someone who lovingly gave me a heads up!
