A few hundred thousand years of evolution has overcome many obstacles; there's nothing special about this time period to indicate that M+F relationships are in trouble. Nor is it historically unique.
I think it's also too easy to focus on relationships in the UK/USA/the west generally, and with relation to ASDs "now", but it's not a global phenomenon.

Thus it ever has been. Also, with the
