Dear Prudence,
I am in love with and in a relationship with my best friend. She’s married with children and so am I, but we are both miserable in those marriages. She is truly my equal; she makes me laugh in a way that I have never laughed. She challenges me in a way no one does. Quite simply, she makes me happy in a way I have not been in a very long time. Not to mention, we have the best sex of our lives. To make things more complicated, we are in a long-distance relationship, so the time we do share in person is special to us both. Time spent apart is difficult. I cannot bring myself to leave my wife and children, nor to ask her to leave her husband and children. Is what we are currently doing sustainable?
