Living a "balanced life" is a challenge for most people.
Those who are in demanding professions are required to put in long hours in order to climb the ladder or remain at the top. (I believe the key to any successful marriage comes down to selecting the "right mate"). Naturally someone who wants a partner that is home for dinner every evening and available each weekend should not marry a person who strongly identifies their well being to their profession.
One of the purposes of dating is (Due diligence), learning about a potential mate's goals and desires, observing them under stress, and deciding if you are compatible. Each of us chooses our own friends, lovers, and spouse. We can't blame professions for the divorce rate. It goes back to (our selecting) someone who has our same values.
Everyone has their own priorities and the trick in life is to find someone whose priorities line up with yours. There is no "right" or "wrong" per se in relationships. There is only "agree" and "disagree". Ultimately we are all looking for someone who "naturally agrees" with us.
