An oft-repeated truism in the polyamory community is, “Love is infinite, but time and energy aren’t.”
Often this is brought up in the context of people who excitedly overcommit themselves romantically and/or sexually, spreading themselves too thin across multiple partners, resulting in a state sometimes referred to as being “polysaturated.” I know that this is something I thought a lot about, for example, when I was dating a profoundly introverted man who was trying to juggle three girlfriends while also needing a fuckton of alone time every week: his love for the three of us may have been infinite, but his time and energy absolutely were not.
