Would you date someone who does not mind a polygamous relationship or and open relationship?

I’m actually more interested in why you would like to or not.

But in my opinion I just don’t understand and it makes me wonder about what he values in a relationship or in women. Is he interested in making a women feel like the most important person in the world? Or he’s more interested in seeing himself benefiting more from feeling like the most important person in the relationship by having 2+ girls that he will benefit from. So does he see it as a benefit thing . Does he not care about sharing so he sees me as equal no another girl. I don’t get anything of it. I don’t understand how I could I continue a relationship with someone who thinks this way and just wants it both ways and doesn’t pick just me over anything everything. Am I not enough?
