Waywardness is born in the heart.... the majority of WW's are M to a man who has the nice-guy syndrome.
This really resonates with me. I think because my W has poor impulse control (BPD-like condition), being paired with me -- whom she's accused of being overly self-controlled, smothering/mothering/suffocating/sacrificing -- she's had to exert hell of a lot of self-control on herself to "keep up" with my role in the marriage. So when she finally decided she can't do it any more, there were years of frustration pent-up inside her that is fueling the waywardness, the rebellion, in her heart.
It's of course, a mixed bag. I think there is a rational part of her mind that sees the good in me and the good in our marriage. But it's mostly covered by the fog of rebellion and hope for independence and freedom from a suffocating husband, and the promise of excitement from new men out there.
