Challenge regarding Christian morality

[Esquilax]

You've identified a problem where couples stay together and fight all the time and it's worse for the kids than if they separated. This is where christian teaching comes in. They have fallen out of romantic love for each other. But if they had the "real" love for each other and the children, which is the love we're supposed to have for all people, they would refrain from fighting and instead demonstrate "true" love. This love is shown by giving up their desires to "get back" at each other and instead live in harmony for the good of the family. We do this in other life situations all the time. This is what we're called upon by God to do. Often relationships are healed in this way, but again we must act counter to our own desires for our own immediate gratification. Morality seems to most often occur when we act against what our natural tendencies push us to do.

So basically you attempt to resolve the problem by defining a second, "real" type of love into existence by fiat assertion, without demonstrating that this love for all people is even possible, and... that's it? Problem exists, just make up a type of thing that solves the problem, and in your mind the problem is solved merely by dint of the fact that you could manufacture an answer out of thin air?

How do you know this "real" love is a realistic proposition for an average person? Or that it's even helpful or productive in the least?
