Dear Mary: A colleague confided in me that he is also gay but can’t accept it so is marrying a woman. What advice should I give him?

Question: I am a single gay man, 40 years of age. I am “straight acting” so any new people that I meet assume I’m married to a woman and possibly have children. It does get tiring having to tell people I’m gay but I’ve become so used to it now, I “nip it in the bud” before they ask.
