CMV: When a person says they can “love more than one person at the same time” (romantically) they really mean “I can get what I want from more than one person at the same time.”

In reading about and hearing people talk about open marriage, polyamory, non-monogamy, I often hear the statement "I am capable of loving more than one person at the same time." My skepticism of this is that when people say "love" in this context, I think maybe they mean "be attracted to" or "get needs met by." To me that's not the same thing as love, which requires self-sacrifice. Can you "be there no matter what" for two, three or more people at the same time? People who live in different households? Similarly I have heard "love is not a pie where the more I give one person the less there is for another person." But time, attention and resources ARE a limited pie. Can you really be a loving partner to multiple people the same way you can to one person? Does the answer change if you live in the same household with more than one partner? As a nonmonogamy skeptic, I'm still aware that there seems to be this minority of people who insist it's the natural way for them to live and seem to "make it work" somehow. I'm not in favor of restricting it, but I'm a skeptic of it.

Please try to make your case without analogizing to having more than one child or loving both parents. These are very different kinds of love.

First, non-monogamy is an umbrella that includes open marriages and polyamory. Open relationships are not about loving multiple people, but rather about meeting the sexual needs of both partners. Polyamory is about loving multiple people. Both have many opportunities for exploitation (as do monogamous relationships), but they are not inherently exploitative.

You seem to understand that love involves a good deal of *giving*. Your premise is that it's hard to give enough to one person, let alone more than one. But this isn't necessarily true - not everyone needs the same amount of  time, thoughtful gestures, or physical intimacy to feel loved. So if you have a partner that does not need as much of those things, it's possible to devote adequate resources to another person. People in healthy non-monogamous relationships often place higher value on trust that's built up through familiarity over a long time, rather than over a short but intense period.
