Thanks for the clarification - I wasn't sure if you meant that a metamour's time constraints were impacting your relationship, but this sounds much different.
I may be mono, but isn't part of having a poly relationship embracing the variety and differences among your paramours? If my partner doesn't like camping, I could theoretically date someone else who DOES like it. I don't see the point in asking everyone to fit the same mold.
Mono. Divorced, two kids (DanceGirl, 15; and PokéGirl, 12), two cats, one house, many projects.
My partner. Poly. In relationships with me, Xena, and Noa.
Poly. In a relationship with Chops. Dating others.
Married, Poly. In a relationship with Chops.
