I prefer having two separate households.
My kids and I travel between my two homes.
I am too Alpha to share my home with another adult female. My husbands are the same way. The only way that would change would be in the event of a zombie apocalypse or a Mad Max type situation.
40 yo straight female
Married in the eyes of the government to Butch since 2001...
Murf my monogamous second husband has been with me since May of 2012.
In a V relationship with an average 60/40 split of time. Only due to Murf's and Butch's crappy work schedules.
