Not quite on the judgemental, I'm not saying in any way that abuse is ok. Not at all. I'm saying that the two of us, who don't know each other, are talking about a third person whom we've never met. And based on a few comments you appear to be drawing the conclusion that her enjoying spankings now means she's reliant on abuse and can't think for herself. I'm saying I have absolutely no idea as to her mental state and will not speculate on it.
I've had friends (far too many of them) who've been molested as kids, beaten, two tortured, several raped and cut up. (Not keeping tabs, I just seem to end up in interesting crowds). And I have (thankfully) plenty of friends who have not had that happen to them. No, I absolutely do not condonenon-conscentual abuse on anyone, of any age, of any gender. Ever. I've also seen the people who have been through it come out as fully capable adults, strong, able to make their own decisions, and I provide them with respect by not second guessing all their actions through the filter of victims. And some do enjoy kink, and some don't. Some like to be on top, some on bottom. Some are using it to work through what happened to them by experiencing it in their own terms instead of those imposed on them, some do it because it feels good, some are exploring themselves, some happened to end up with partners that had that kink and they pursued it. And I know just as many in the non-abused category who enjoy the exact same things.
I'm not saying there are not some unhealthy people pursuing kink, of course there are. People who have been through trauma reclaim themselves in many ways - joining the police, becoming therapists, working out, overeating, etc. I'm saying we cannot assume anything someone does is bad / they are incapable of choosing for themselves just because somewhere in their life they had a choice removed.
And really, being a house wife to someone she loves, a mother, and enjoying lite spankings is the end-all symptom? That's what there is to worry about? Sorry, that's not even on my radar of self-harming actions, and I can point to a slew of housewives and mothers who would picket anyone saying their choice was not legitimate.
In summary? I have no clue as to her motivations (neither does anyone online, and even in person I would not accept the diagnosis of anyone who is not a therapist), her choice is not bad (even if it is not what I would choose), power exchange is a lot more complex then on law and order when practiced 'correctly' (serving to protect everyone involved), and I'm not saying her choice is right or wrong - only that it's entirely her choice (even if the choice is to surrender choice - something everyone does to the same extent when they join the military, and we don't blame them - and their risks are Far more dangerous and hard to opt out of later).
