I didn't push for an expensive engagement ring, I've already said mine wasn't expensive. And actually in interests of transparency, I thought me getting an engagement ring and my partner getting nothing wasn't fair and so I bought him an engagement present. Not a ring because he didn't want one, but something sentimental which he values to this day.
If my DH had told me that he though engagement rings were outdated symbols of the patriarchy and he would prefer not to give me one, or to exchange other gifts I would have been fine with that.
If my DH had told me that he thought rings had an environmental impact he was uncomfortable with, or he was concerned about ethics (my diamond is lab grown) then I would have been fine with that
If my DH had spend £20 because that's all he could afford I would have been fine with that
If my DH spend 100s on his clothes and 1000s on his watches and £30 on my ring I without any conversation I would have been concerned that he didnt value me.
And I outearn my husband. But that's not the point. The point is that women disproportionately take parental leave, disproportionately care for disabled children and family members, women disproportionately had to give up work during the pandemic due to childcare issues, women are disproportionately affected by the gender pay gap and women are disproportionately impacted by domestic violence and abuse
You want equality, start campaigning for better paternity leave, sure start centres, more uptake of shared parental leave, respite for disabled children, better cheaper child care, close the loopholes that allow self employed men to skip out on CMS, a better CMS system, a benefits system that doesnt penalise single parents, rather than moan men having to buy an engagement ring is unfair.
You said you were playing devils advocate and in a random conversation around whether engagement rings should still be a thing I think it would be an interesting debate.
But you have a group of women warning a woman that she might want to see this behaviour as a red flag, it could be a sign of future domestic violence and she might want to put it in the context of his other behaviour and see if its a cause for concern.
And then you come along and say 'oh devil's advocate here, in a completely different situation i did something similar so you dont need to worry about abuse stop being a gold digger'
If you think that's a moral, ethical stance to take, given 1 in 5 women will be financially abused then fair enough. I'm not keen on 'intellectual debates' when it comes to an actual individual situation
And finally it doesn't matter how much women, or men for that matter, earn they can still be financially and domestically abused. Being the breadwinner in no way stops that from happening. If you think outearning a man is enough to stop him from abusing you I would politely suggest you do not understand domestic abuse.
