A couple friend of mine act in this way.what does this mean?

this couple is married for 3 years(my male friend was a playboy nd is quite rich).my friend takes her to some events but when they are asked to pose for pictures they just stand together and pose without holding each other by the waist or shoulder or anything but when the husband poses with other women he holds them by the shoulder.and he keeps talking about his 2 yr old daughter and has posts only his daughter and his own pictures on social networking sites but doesn't mention his wife at all and rumors float around that his wife has had a baby with somebody else.he has a tattoo with his wife's name but its hardly visible.only if you through a lot of light then its visible .once there was a pic with his wife in which he did hold her by the neck with hands entwined but in that too he was looking elsewhere and it looked very artificial.a week ago they went for some formal event where again the wife posed with her arms folded while my frnd had his hands in his pocket though they stood together.whats this?
