The duties of a husband.
I'm writing this from my own limited understanding of paraMparA & shAstras and what I've observed the elders and the society, community. Ofc not binding upon anyone. https://twitter.com/Shakra_Kulish/status/1296374912949469185?s=19

The union of pati and patnI is sacrosanct and permanent thus made by the dEvas represented foremost by agni . pati & patnI both words mean the owner of the other. So at once one is the owned one as well as the owner, a system unique to Hindus only, thus we behave accordingly.

The seven vows during the vivAha saMskAra are the foundation of the Hindu marriage, unfortunately we neither listen to it during the rituals nor do we care about it later on. But I'd go into practice of it in today's life.

Pati mustn't have a roving eye, even if it was the case it must stop. His sole interest should be his patnI, the lover as well as the partner. He should be devoted solely to her in this aspect.

He should praise her for the good things and keep the criticism for pointing out later in private, not immediately or in front of others. pati should be gentle and caring to the patni, firmness is needed only when there's anything going against the relation or family.

Her parents should be given respect like his own parents especially because in modern era owing to circumstances her parents would happen to spend time more with the beti damad than own home as in today's increased longevity & late marriages the health of in laws too is priority.

pati should help in the household chores which don't require much finesse or skills yet more labour like cleaning etc. Eating out should be restricted, he should ask patnI to cook whatever she has learnt previously & gradually add his choices to it. Ensures bond & responsibility.

He should not disrespect/abuse his own parents else it'd make her ingulge in same with time. If they don't live in the native belt then intermittently must visit there with kids, participate in rituals & community gatherings accordingly to feel belonged to the ancestral place.

Pati must observe nityakarma as much as possible, at least morning evening puja must be done daily. All major festivals & the ones unique to their region must be celebrated within the constraints of livelihood. If possible leave should be taken when there's no official holiday.

Both must have a joint account from the very outset. Both must know each other's passwords to mobile, SM accounts, bank accounts, everything. He mustn't discourage her to study/work if she insists but should persuade her to not take up anything which disrupts the family.

He can do difficult jobs yet tell her that the grihiNI is the sheet anchor, foundation of home so she should stay away from any job which compromises the basics. Occassionally he must surprise parents, in laws, her & kids with gifts, excursions. Temples must be visited regularly.

Involve both sets of parents in cases of conflicts not solved mutually. Better should keep silent a few times in cases of arguments as the anger on the other side could be inconsequential and transient, mostly. Most difficult: better not shout on kids, don't be too friendly too.

He should maintain an excellent personal hygiene, need not be in style or fashionably groomed though but should dress properly and do physical activity / exercise to not get out of shape. Should get her involved with himself in jogging, yoga, outdoor games within constraints.

The onus is on him to provide a dhArmika environment at home with narration of dhArmika, paurANika legends.. books, audio visuals and rituals by oneself, kids must be told about svadharma and everything must be led by example. He mustn't let English be language inside home.

He must take his parents to important tIrthas at least once, with her and kids, could take her parents together too when possible. If not possible to complete tIrtha circuit, visit the nearest one at least. He should seek kulaguru & worship kuladEvatA, kuladEvI & grAma dEvatA.
