It really isn't. In the situation OP describes, she is simply encouraging women to control their own destiny and end relationships with absolute dead beats. Women are more than capable of reading, processing and reacting to warning signs. I absolutely hate this mindset where women are weak, feeble creatures and it's entirely a man's fault why the relationship is shite.
In order to be able to read those signs you have to have been raised in a family with a healthy dynamic. I wasn't. My parents were lovely to me and DBro, but they had their own dysfunctional behaviour that I grew up thinking was normal. My parents weren't abusive or toxic in a nasty sense, they just didn't have a clue. I did have a lot of love, though.
When I met my ex, I was a clueless late teen. There's no way I had the skills to be able to realise at the time that this man wasn't a peach but a wanker. It took me 30 years to get out of that relationship, and while I now have those skills and have my shit together, for years I was stuck in the mindset that you have to work hard at a relationship, that men are generally useless, etc.
I can see now that there were red flags from the start, but at the time, I simply had no idea. I did have DC with ex, and now that we are a family of 3, I am teaching them the relationship skills I lacked when young. I've also read plenty of threads on the Relationships board, including those stickied at the top. I've dropped examples from there into conversations with my DC. It must work, as DD dropped a bf who was showing red flags, without me needing to gently raise it with her, which I would have done if necessary.
So really, I think
a) We need to be teaching young women what a healthy relationship looks like, because if they come from a dysfunctional background they won't necessarily know.
b) We need to be raising boys to be decent men, who have healthy relationships.
c) We need to be countering the toxic ideas still prevalent in society that relationships are always hard work and that men simply can't be expected to be decent blokes. Wifework should simply not exist, it should be teamwork.
