I want to write on it for a very good reason; mine is not good. I hope no one including her will take what I am about to say as bad form or taste.
My Marriage is "not good", not because she is bad or even wrong for me, no that is not the reason. Nor, is the reason because I am abusive or a jerk or any other superlative you can come up with. The reason is because I and she are human beings we make mistakes, we do dumb things that hurt each other. We have moments of selfishness, sometimes extreme selfishness. We have ideas and attitudes that often do not agree. Those things do not make a marriage bad or good.
What makes or breaks a marriage is how we handle the ups and downs of our fallible, sinful, lust based human condition. Can we rise above it and as Jesus said "Love each other as I have Loved you"
How exactly did Jesus Love His followers?
Well, we can see how He put them first over his own needs except when to do so would harm them or his Fathers purpose. We can see at the arrest in the Garden He did not allow his followers to take heat for his decision and actions. He provided what was needed. (paying the temple tax for example). When Peter denied him he did not deny Peter. He taught that a person must forgive as often as the other person repents, even if it is for the same offense (Matthew 18).
Jesus though he never spoke directly about Marriage except to say that Marriage is for life and divorce was to accommodate our sinful natures and is only tolerated by God. not approved. Did in fact lay down the basic principals that should guide our marriages as well as any other human relationship.
One of the prophesied functions of the Messiah was to "interpret" the Law, He did this when he was asked what is the greatest law of the Mosaic law by an attorney,
"Mat 22:37 Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.
Mat 22:38 This is the first and great commandment.
Mat 22:39 And the second is like unto it, Thou shalt love thy neighbour as thyself.
Mat 22:40 On these two commandments hang all the law and the prophets".
Lest any of you misunderstand I do not consider myself a great and loving husband, I have problems as is demonstrated by two previous marriages. I am doing the best I know how now, to allow the Holy Ghost within guide me into better and wiser decisions when conflict arises. I forgive my spouse quickly and ask her forgiveness as quickly as I discover where I was wrong. In short I do the best I know how, to Follow the Master.
Is Marriage a 50 / 50 deal? The answer is absolutely not
Marriage is a 110% by 110%, deal. Each partner is to put all of themselves into the relationship. The relationship must become the top priority. Your spouses needs and wants, must be considered before your own needs and wants, not an easy task but not impossible either. When your spouses needs and wants are more important than your own and hers are less important to her than yours than magic happens and Love grows and blossoms, and all needs and wants are meet or shown to not be as important as we thought them to be. But when one or the other always puts their want or needs ahead of their spouses only conflict can happen because each is trying to take something from the other that the other is not willing to give.
I will close with this. Conflict in a marriage or any other close relationship will happen, it is unavoidable, however, scripture has an answer for when it does occur, "James 5:16 Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much."
Please pay attention that the passage does not say confess your partner's faults, it says "confess your 'own' faults to one another", then pray for each other. Fault finding of your spouse does not belong in a marriage, it will destroy trust and respect. Look for what is good in each other, even when you are mad, it can be found, focus on it. Jesus even on the cross found good in us, surely your trial is far less painful.
Bottom Line is Love is what keeps a marriage together, Forgiveness makes it a pleasant journey.
May God bless you and keep you with all the blessings He has stored for you.
