It's definitely weird.
I'm not sure I would love my wife gossiping about my batshit family to random middle school friends on facebook. Maybe some things should stay within the family, especially if you're worried about what your parents do and don't find out.
Well she was only talking about her Anti-vaxxer and Q views which my SIL puts all over FB.
How much difference would it make if it was all private instead of out in the open?
If you only have two choices, would you rather they be together and swing, or be divorced?
Do you think this satisfies their sexual needs, or will they continuously need something more?
Quite frankly I don't think their marriage will last. They are ignoring the problems with this and potentially creating new problems.
I can tell you they are ignoring the problems because my brother's drinking habits were an issue and he had apparently stopped doing that for a while for her. Well he's started back up. He's also back to smoking over vaping so his whole family can breathe in that nice second hand smoke.
I think this kind of makes their marriage a sham anyways and I think it's like trying to lose weight by eating more calories and doing less exercise.
