Of course. In a poor relationship, women will often end it at the first sign of trouble, in a good relationship, women will persevere, offer support, sometimes for a long time. But eventually, if things don't change, she'll reach the limits of tolerance. Meanwhile plenty of men strive to be successful enough to support their woman, even without children, and make work optional for them.
The few "kept" men I've known are in very weird relationships, in which he seems to be perpetually walking on eggshells and utterly disempowered, and she seems to be perpetually mad at him.
