Do you believe in monogamy and why?

To me if a couple is non monogamous they love each other so much they want their partner to have all the best experiences and trust each other more since they know they’ll always come back to them.

For this question what if we take relationships or if it, and if you and your partner are non monogamous you simply have casual encounters with others and not another relationship altogether, does that change anything?
