Humans weren't meant to be monogamous..especially men with resources like Mamoa. Dude has plenty of women who can fulfill his needs and he has the means to provide for them.
In that day, seven women will take hold of one man and say, 'We will eat our own food and provide our own clothes; only let us be called by your name. Take away our disgrace!' " - Isaiah 4:1
Some of us are given the blessing of having more than one wife.
It's all over the Bible and biblically there was no end to being allowed to have more than One wife.
"But having 2 wives causes problems"
"Most men can't handle 1 woman
"
If you're equally yoked on the same page and marry who you believe God is telling you to then its much easier doing it.
With that said...I'm not marrying...I'm selfish and want to accomplish shyt..but monogamy wasn't meant for some.
