Dear Queenie,
I had an affair with a married man whose wife was dying of cancer. It went on for several years and I thought maybe after a period of mourning he would ask me to marry him, or at least come and live with him, but it turned out that he just dumped me right after the funeral. Then, about a year later, he got engaged to some other woman.
Queenie, what do you think of all that?—Puzzled
Dear Puzzled,
Maybe after his wife died he felt so guilty about having cheated on her that he could not go on with you. Or maybe he needed the “forbidden fruit” aspect of your relationship to make it work. Or maybe he just got tired of you, or maybe he is just a jerk.
