Let's Scroll back 16-17 years ago.
He gets two daughters with the wife.
That he wants a son is understandable, but why not Try again instead of Adopting?
And why adopt from vietnam? Why not adopt a normal USA son? And why Three?? Is it not enough with one Son?
And then, after he now has Sons, not one, but Three, he isn't satisfied at all, but leaves the whole family and children to be with his wife, and just disappears someplace to be gay instead?
Very odd behavior.
Maybe he molested those boys and bailed or wanted too...just probably increased his gay tendencies being around them and couldn't deal with it.
