This is just WW garbage. What she said is really: "I want you to find another person so that I can feel good about the other person I'm cheating on you with."
Plenty of people find ways to have fun and still honor their marriage vows. The two aren't mutually exclusive.
That's how I've taken it. She's said this a few times recently. I think she does feel guilty going out, both about me and about our D2, and thinks she'll feel less guilty if I'm doing it too.
Also: "I want to be happy. I want you to be happy too."
