My Husband Is Sleeping With My Mother, what should i do?

My mother is an attractive, interesting woman who dresses fashionably. Recently, I found out that my 39-year-old husband has been having se’x with her when he attends conferences at the resort near where she lives. When he told me, I was bothered by the fact that it didn’t bother me.




He’s a wonderful man—father to our two children and a good provider—and he’s always taken care of me emotionally, se’xually, and financially. I know I should be upset; I know I should feel betrayed on so many levels. But I just don’t. He says he enjoys the relationship with her but will stop if it’s what I want.

Honestly, if my mother and husband are happy in their affair, I just can’t seem to find the energy to be angry or jealous. So my question is: Is this normal? Should I be upset?
