The problem is, at the moment society allows ordinary men to be a bit lazy and grumpy, and expects women to help them manage. Women are trained to fill in men's gaps. We are socialised to be support animals.
That means that a base level of inadequacy is considered the norm. If you find a partner that's truly equitable then you've 'bagged a gem'. Caught a good 'un.
In turn that means that the early behaviours are overlooked. Slightly petulant? Grumpy if his sleep is broken? Irritable about money, or disappointment? Must be stressed. Soothe him, support animal/partner.
By the time you realise this one is dangerous rather than typical bloke eye roll, it's too late.
Boiling frog.
