I think we all know that the marriage is based on money... she cannot like, let alone love him... she has a son, smart move cos he will always pay and care for his son.. and for her.. They may well stay married but lets remember while he DOES love his son, and all his kids, he HAS by his own admission cheated on Melania. He's using her as a pretty toy.. she's using him for his money - I think he has the better deal honestly there..
I think too she would welcome him being away while she stays with her son... who wouldnt
