I think happily ever after is definitely possible, but fraught with peril.
I know 3 providers I could easily imagine being married to, but for the age difference and the fact that I am happily married lol. Each of those 3 is very smart and someone who could be my best friend as well as a skilled and creative lover. Each of those 3 providers is bi and can't imagine being limited to one partner. I have been and am fine with my partner having other partners, and sharing would be cool as well.
In the alternate universe where I am single (and perhaps younger), I would love to meet and marry someone who is as sexual as I am and who thinks, as I do, that monogamy is unnatural--and someone who is a kindred spirit and soul mate aside from the sex. The latter is likely more important than sex in having a long lasting and health relationship. A lot to ask for, but not impossible--perhaps not any more improbably than finding all that in "civilian" life.
It is hard for me to imagine a hobbyist and a provider marrying and making monogamy work.
