Nice thought and a nice question too.
U have explained most of the things people do which sometimes leads to burden overwhelm by one partner. In my own opinion, companionship shouldn't be a fifty_fifry or zero_hundred, but it's should be a matter of standing for each other when necessary. Both parties have a role to play because the holy Bible says both the man and woman are to leave their parents and establish their own homes, so if you are leaving Ur father's house to build a new home, it's expected of u not to come with an empty ideas, empty tolerance, and zero mind to contribute; because the left hand washes the right hand and vice versa.
