Frankly the balance of a relationship is upset when one becomes less able and the other's role morphs into that of carer. It may be possible to either just grit your teeth, count your blessings and KBO as Churchill used to say. The frustration experienced by the less able partner, feeling useless and dependent, can also be draining on both parties.
I have to help DH get dressed these days, clear up after his shower, prepare all meals and clear away etc afterwards. He can't carry things upstairs as he needs both hands to support and balance. If I am being honest, he did rather tend to be less than "hands on" to put it politely, but to be fair, he has not known -good health in the last 25 years -sometimes a little bit better, sometimes a lot worse!
But to return to my point of balance, the partnership is no longer equal but it can be complementary.
I do not know the extent of your DH's disability but cheerful chat while you fulfil your domestic goddess role may still help him to feel useful. You will both grow into your "new" roles, but in a different way. Good luck!
