I am single. I was fortunate enough to find a partner who taught me a lot about myself and about relationships. In the end his drive to control my life was unlivable, but I won't downplay the connection we had - and still have. It's a big reason I've chosen to remain single. I don't believe I'll find that kind of connection again.
As far as relationships in general, I think the piece the gets left out of these conversations is the fact that until VERY recently women were basically forced into them. And then couldn't get out of them. And men abused that control in all the worst ways.
We are only now discovering our freedom. And we're angry about the abuses we've endured because society told us we had to.
So yes, do men and women both have issues in relationships? Absolutely. But men weren't forced to be domestic baby-making labor, often under threat of violence or homelessness/destitution.
It's like telling the black man, after he won his freedom, that he needs to sit down with the white man and discuss their issues with each other, because, you know, white men have complaints about black men, too.
It's the power dynamic that's the problem. Women couldn't hold a mortgage without a male cosigner until 1974. Literally 50 years ago.
So, yes, are women poor partners just as often as men are? Maybe. But we've also been forced into the institutions of marriage and parenthood for millennia when many of us definitely would not have chosen it for ourselves.
