As soon as I saw this I knew the predictable course the story would take through the usual media and I thought "I hope there's a thread on Mumsnet where people are being sceptical". Thankfully, yes.
This looks strategic in terms of PR given the bad feeling on the sofa stories that were brewing, I also suspect a tabloid in the wings. Much of the 'entertainment world' is coming out in social media support of his bravery according to the BBC, who are also running a handy 'what it's like when your parent comes out as LGBT' panel with a smiley family on it.
PS isn't so old that he was forced into the closet, he may well not have been brave enough to risk being sidelined in his telly career though. I am very sceptical of all this ooh sexuality is complicated etc. That's only something I feel sympathetic to when people have made decisions which protect others from their 'confusion'.
I feel very sorry for the wives and families of men who suspect they are gay but who marry (and I mean with the assumption they are straight, not a 'lavender marriage') and have children, then wait until middle age to 'come out' to applause.
This exact scenario happened to a friend of mine some years ago and it unravelled her whole life: the worst bit - and where it was different from common-or-garden cheating - was the realisation that he had used her as a way of repressing his feelings for the sake of his career, so all the past was thrown into doubt. It turned out, though, that he had not been able to entirely repress his feelings to other men but was able to get all that off his chest when he came out to sympathy and understanding. He's fine, with his husband and his financial cushions and his bravery. She and her boys aren't, but there is no space for them to express that.
