Wow !! Amy,you said a lot. Weren't you the one expecting a full swap at Eric and Layla's apartment. They look to me as committed couples too. Going by your logic you expect them to go ahead with that 'filth' since they are not married.
Have you not heard of swingers or open marriages ? Mika was the one who initiated it and they both looked happy. As I said earlier, I don't want to comment on anyone's personal life but calling someone disgusting and filthy and giving a lecture on morality and weddings on this forum is absolutely uncalled for.
End of discussion I hope.
