Whats wrong with this couple and their relationship?is their a complicated one?

my friend is 31 and has both his wife and daughter's name tattooed on his arm but his daughter's name is artistically done with flowers nd doves dedicated to her while the wife has skulls made near her name.though he brings her to public events every time except official events he never holds his wife on the waist as a couple but does hold other women by the shoulder or waist,once they posed with my friend holding her by the neck like that in a pub holding hands but it looked as if he was strangling her and it looked very weird.they are married for 4 years now.and after marriage he seems pretty stressed and quiet while he was very jovial.recently he was seen without his wedding ring but after a few days he was wearing his ring again.he also likes psychopath pple in films,loves ghastly designs and black on clothes and has left st Louis to live in desolate high ridge.hes very rich and was a playboy before, his wife is a gym instructor.
