Bumpitybumper I was reflecting on that point myself - I am talking about abuse and the thread is about useless. My first co-habiting relationship was with a lovely, funny, but domestically useless man. He drove me to distraction in the end, and basically his parents always stepped in to do stuff for him. You could argue that is just close family and his family had quite traditional ideas which I did not fit. We had our arguments and in the end he found someone to take care of him, if that makes sense, and the parents are still there helping out.
But I can talk to him without being triggered and I do not feel abused by him. We had different goals and needs in life. However, he did exploit my domestic labour to continue to live in his bubble of not worrying about things.
Paradoxically, xH (the abuser) was extremely self-sufficient and competent with things and that is why I thought he would be a better bet 
So my conclusion on reflection was that my criteria for non-useless led me to extremely efficient sociopath. And I was not brought up to spot them! Whereas now, if you watch Frozen, Prinz Hans is the sociopath.
However, I also think my xH knew how to exploit society’s ideas of what a woman should be and do (domestically) and the idea of the good mother - which are the same ideas which let my first xP be useless, if that makes sense. But xH did it to undermine me and exert power, to make sure I was always busy and had no time for other things, he would make comments if I wanted to do different things and punish me in various ways. Whereas cohabiting man, while outwardly useless, would not bat an eyelid when I went to the gym three times a week, or if I was not home by a certain time or went out with my friends myself. The housework would only occasionally get done in my absence if I asked, but my freedom of movement was never restricted in any way, he did not undermine me and consent was always fully respected - mostly I remember him as fun. I don’t feel traumatised still by him.
But I think the point is that the same societal power imbalance and sex-based expectations underpin both experiences. And with relationship 1, I arguably started off with the idea that cleaning the house was my job because I had a routine from my previous flat of when and how to do it, whereas it was his first time living alone.
I don’t want this thread to become about my experiences, just reflecting on it - xP was benignly useless in the definition of the OP, xH was not, but both operated and used (maliciously or not) society’s traditional ideas of a woman’s place as wife and mother, which is based on inequality.
