its is regressive, yea.
But i think what he meant for it was that, even if she's having a tough day at work or what, she will always have a home or place to crash at. Like a safe haven to unwind and relax after a tough day at work. She's actually pointing that she doesn't have to stress about the things at work, rather than "you don't need a job, i got you" point
he surely don't have that "she should stay in the house" bullshit mindset like trad wife agenda

guys what does ichikura mean when he says "you'll get married one day so I don't think you need to worry so much right?" is it me or does this sound so regressive?
