Put God at the center of your family, don’t abuse each other, don’t commit adultery, don’t be selfish, show love and affection for each other and always put your family first.
Absolutely.. If both are unwilling to work on the marriage or it’s completely one sided, it will not work no matter how much one person is willing to put into it.
I have seen so many marriages fail for that very reason. A lot of people expect everything to be perfect and always given to them and not have to work at anything. They fight or leave when the slightest problem arises. Marriage can be very hard, but can also be very fulfilling if both are willing to work at it.
My advice though, is very basic advice.
