You can tell just by watching Mariah interact with people for 30 seconds how up in the clouds she is living. The diva attitude is great for TV, but when you're like that 24/7, that's a mental issue. I feel like Mariah has people bowing at her feet all day and she lives for it. Every time she has a problem, there's probably someone on her payroll to fix it for her, and you can't have your employees fix all your personal problems. As much as Nick is obnoxious and annoying, he doesn't seem unstable at all and seems like a really down to earth person unlike Mariah. I still don't understand how they lasted long enough to have children. This is why I say not everyone should have kids, both Mariah and Nick have the mindset of a 16 year old.
