First of all there is no such thing as being 'gay'. It is entirely a behavioral choice. Of course this choice is influenced by an underlying mental illness called Same-sex Attraction Disorder (SAD).
The question is "why, after all these years, is this guy choosing a life of perversion"?
My guess would be that prior to the detachment starting her husband became addicted to pornography. Heterosexual porn gave way to child porn gave way to homosexual porn as he became desensitized to normal desires. (That is, he got used to regular porn and needed to try something else to get his fix).
After becoming addicted he then reached out to try the behaviors he saw modelled in the porn. He probably had been molested by a man in his childhood or neglected by his father so he had an unfulfilled need for masculine attention (these two causes show up in almost all people afflicted with SAD) and his need for something new sexually combined with his need for masculine attention overwhelmed his common sense and morals.
He basically abandoned his family and everything good just to get a cheap sexual thrill.
The absolute worst thing that his wife could do is encourage and support him. She needs to practice some tough love and shut him out of her and the children's lives immediately.
Statistics show that those who succumb to SAD are also from 13 to 40 times more likely to be child molesters also. The risks just aren't worth it.
The children would be better off if their father suicided physically instead of morally as he has done.
God I pray that you will restore him to his senses, save him and deliver him from perversion.

You need therapy. NOW.
You got THAT right. We need to stop being enablers, let alone co-dependents, of the SADs.
Shalom.
