Mark mentioned a couple of things that I would say are
massive red flags.
When he asks Nadia what her plans are for a certain day she
flies off the handle, and if he asks her what her loud, dramatic, animated phone conversation was about she tells him, "
it's none of your business"!! Omfg! Wow
There are no secrets in my marriage, I regularly ask my other half what his plans are and what his conversations were about if it's clearly concerning to him, and he NEVER tells me it's none of my business and vice versa. IT IS my business when our blended family is concerned or our friends.
Also we know each others passwords to everything.
M & N have such a dysfunctional relationship it's mind boggling.
She's the abuser, controller and manipulator.
If Mark reads this, I'd strongly advise him to get marriage guidance from someone that isn't his own controlling wife!!!
