I'm torn, probably as Mariah is. On the one hand, they do seem to really love and care about each other-- and their family is beautiful as a unit. We've never gotten any confirmation as to what ended the marriage, but I always assumed Nick cheated? Which, if true, would make it nearly impossible to trust him again. If not true-- what would be different? Making more time for each other?
I worry about their age difference and the fact that Mariah has weight issues-- I don't know if it would drive her crazy keeping it together for him.
I don't think anyone can deny they have a special chemistry together. It would be amazing if they could actually make it work.
