I'd be sad, but would be happy for her.
My wife's happiness is important to me. I love her, so I want her to be happy.
If she's miserable with me, and isn't genuinely sexually attracted to me, because of my love for her I wouldn't want to keep her from being true to herself.
This woman likely wouldn't have spent 20+ years ago if she wasn't in a cult that made her afraid of coming out.
