Supposedly I read that, the deal was Melania was to give him another child, maybe this time he thought he would of been better at it.
Trump failed with Ivana Trump, in that divorce she has full control over the children until they graduated from college, then Donald was suppose to teach them the business world.
Marla Trump had none of it, she kept the child, raised her by herself, and Donald would have no influence over her, and he has pretty much done it that way. Of course he pays the bills, but that's it.
Melania is also raising Barron on her own, and that is why she is so protective of him, would not surprise me if she leaves the White House after this first year and returns to New York.
