Some awful posts in this thread, it amazes me that some people still see others sexuality as so obviously black or white and make all manner of judgements off the back of it.
Found it all very emotional and It seems like he, his wife and his kids are doing their best, maturely and lovingly in a very difficult situation.
As Rel and others stated, sexual preferences don't define a relationship, to say the entire marriage is a lie, waste, sham or whatever else is so ignorant.
I'm quite sure people wouldn't be so appalled, judgemental or insulted on his wife's behalf if it was any other celebrity caught cheating or acting poorly in their heterosexual relationship. Doubt an eyebrow would be raised, and why is that?
