You're right. I completely forgot that Jason was married. I met Jason long after he was divorced. I never met his ex-wife, and he didn't talk about her when I was around him. He hasn't been married for so long that for some reason I forgot he'd ever been married at all.
And I had almost forgotten that by the time Metallica finished the Black album, all of the guys in the band except for James had split up with their wives.
