I find them quite unrealistic as a couple and actually find them both quite irritating. Why does Whitney act like a wife from the dark ages, in not knowing exactly what Lee does for a living or know what he earns and even their own financial situation, surely you should know what money is going in and out of your accounts. Surely this is basic stuff to know about each other in this day and age if you are settling down.
As a woman myself, I just find it hard to believe why she never questions his moods and in particular on their wedding night, you could tell he wasn't happy, not necessarily to do with her but just the situation he got himself into. She just walks around oblivious to it all, not a great start to a marriage when you don't even really know your husband that well!
Equally I know that depression can be difficult to handle but there are occasions where I wish he would just man up!
