Dear Queenie,
My father and my fiancée’s mother met while we were planning our wedding and now they tell us they have been seeing each other for a while and now they are getting engaged and plan to be married next year.
Queenie, is it okay for me and my wife to be married if my father is married to her mother?—Worried son-in-law
Dear Son-in-law,
If your father marries your mother-in-law, you and your wife will become step-brother and -sister, which is not a “blood” relationship and would not prevent the two of you from marrying each other if you had not already done so.
I admit the situation may be difficult to explain to people who do not already know you, but it may even make an interesting topic of conversation.
