That's precisely why making any judgement, good or bad, on someone with such a public personal is rather pointless: You see what they want you see for the most or what others want you to see about them.
Same goes for Melania. She's deliberately moved to distance herself publicly from her husband, it might do with the fact she's pretty angry with him or rather that she sees great value for herself to not be tangled up in his controversies or it might be that she would love nothing more then to divorce him but since she has a child with him she'd rather be a good mother who won't put her boy through a divorce ( and as someone who lived through that as a kid it never ends well when your parents divorce ).
