What a weird thing to say about marriage but typical of guys his age.
I think you may be mis-reading his intended meaning here.
As I read this, he's saying that she wanted him, literally, in a real prison for the rest of his life. In her mind, he deserved it because he wouldn't go along with her fantasy of marriage, kids, and happily-ever-after. She had her (and his) life all planned out and he wasn't willing to cooperate.
You may be right. I wonder if there was any clue to her psychotic nature. I was in a situation where I refused to see certain signs till it was too late. Some men will put up with a woman's bad behavior if she's gorgeous.
Yup, and this is the GREAT FEMENIST AGENDA that is being spread and taught and embraced here in America.
