Uhm?? I’m not too sure, I think monogamy is a realashionship for a short time and on to a next monogamy. As for marriage it’s different it’s more of a stable a more Secure long-term serious relationship. But, that is my opinion!! I myself is not interested in a monogamy I really don’t want to live my life in sin. That is why I prefer to be in a marriage. Thank you Eze, for your question.
