Dear Thelma: Double standards for marital affairs

Dear Thelma,

I would like to pose a question. Hope you will bear with me. Recently, I was a little bit perplexed regarding relationships in a family. I am wondering how one action gives rise to another different set of reactions or results. Firstly, let me give a scenario of a family consisting of two parents with adult sons and daughters, and grandparents. If a husband or wife has an affair, obviously the spouse will be very unhappy and may even file for divorce.
