Question for married people?

Part of the traditional marriage vows/ceremony is "Let nothing come between you". I believe in that whole heartedly. We do not have children, but that even includes them. Hear me out...The needs, welfare, and raising/training of the kids is a very important and necessary responsibility and in no way should be neglected, but the kids will grow up and leave making lives of their own. When that happens, if the parents have devoted all of their time and energy to the kids and not any to each other then what do they have when the nest is empty? Nothing. It is not uncommon for couples to divorce once the kids are gone because they have no real relationship anymore...they've "grown apart". The same could be said for work as well. Of course in an ideal world a person should be able to put work aside every time their spouse needs or wants them but in reality that is impossible. That doesn't mean that your spouse can't still be your main priority or your family either. Some places you work are pretty understanding about certain things when it comes to prioritizing one's spouse/family, but more and more are not and your job is your livelihood (the necessary means by which you provide for said family) and cannot be risked losing. A strong couple with a good relationship knows/understands this and works with it.
