You are describing my great-grandmother, and why do you care?
Polygamy sucks for the women and children. Tell me, how do you think you would feel the day your wife took another husband? Think that wouldn't hurt? Assuming you had any feelings or him? On the other hand, if I was forced to marry a man twenty years my senior whom I didn't love, I'd probably be counting the days until he took another wife and took his slimy self away from me.
