Good morning from Texas! My family set-up is: my father, my mother (his wife), his “main” girlfriend and 2 “secondary” girlfriends which get changed usually every 2-3 years. Yes, we all live together in the same house - though it’s a big house - so it doesn’t feel crowded. It’s not a religious thing at all, we’re atheists.
You’re the only kid? Has this been the setup your whole life? Are there any ground rules or is that part of their life more of private thing you were insulated from?
Yes, I’m the only child. Yes. I wasn’t insulated at all, it was pretty much an integral part of my life. As for ground rules: mom (his wife) was the only one allowed to parent me, I called the other women by their first name, mom and dad always shared a bedroom, with the main girlfriend joining most of the time, but she has her separate bedroom. The “temporary” girlfriends as I call them have their own bedroom and as far as I can remember never slept in the master bedroom. Overall the whole thing is very hierarchical looking at it now. I’m on good terms with everybody.
