I think you have problem more than your 62. Why you expect your 62 to pay for your wedding dinner? You and your husband live together with your 62, of course has the responsibility to doing homework and take care any issues and 屋企既事.
I am not living with my 99 & 62. If there is any 屋企既事, then my husband still need to help such as repair , replace out of order home equipment.
