Would you drive a car without learning first how to drive it? Or fix an appliance without first having googled what to do, or at least discussed the problem with someone who could help remedy it? What about expecting to pass an exam without having had a lesson, lecture, seminar, tutorial on it or done any research on the subject?
No, you say, of course not! And yet, another friend, another relationship, is not going well. One party keeps everything going on, bottled inside themselves, the other talks to all and sundry, but essentially only to vent enough steam to be able to continue the modus operandi. At the moment they have no money for counselling, no time to take a marriage course and have no knowledge of self-help books and films that would help them.
This couple have children. Walking away from the relationship would have caused enough damage to the couple and other people in their lives before they had children. Now they have children the damage would be untold! Any of us in a relationship, even the ones we want to be in for all the right reasons, will on a regular basis neither be, nor have a picnic! To continue the metaphor though, if you want decent meals then you had better learn to cook!
None of us can expect a decent relationship without learning first what a decent relationship looks like, finding out how to get one and then finding out how to keep it. We expect no less for the products in our lives, how much more important then, is it to work hard to fix and operate the relationships in our lives, i.e. the things that really count!
