I am happy for him. I know he still lacks a bit of maturity to give Don the proper answer, he either crash and is unable to real with with or reacts violently. But I believe that with support from the kids and Nathan he will do it. He should have confronted Don with the Fran issue, that we was probably trying it to please Don and trying to be normal, that was the true "phase", not the gay one. It is not because Nathan is girly, we should just tell Don that he had sex with Tom, who was really "boy" (if he doesn't want to talk about Alex). After all, before Fran and before Nathan, he was the guy that chose "gay1" as password for school locker, seems quite sure of himself to me.
