Hi brother,
My prayers go out to you perhaps in a different way. Along with the good counsel of others here that you find a true saint, a pastor to confide in I also believe without a shadow of doubt that there is much right here that will do your heart good and if you will allow it, a great sweeping change of attitude, character and disposition.
It can come in many forms. Sermons. Keith Daniel comes to mind and there are a number of excellent messages on marriage here, they altered my own perception greatly some years back.
But what might really challenge and shape you are those things that we tend to think don't pertain to us often. That is, counter agents. For instance pride. It's opposite would seemingly be humility and it is - but patience, [i]not speaking[/i] when the vile flesh and corruption of these fallen minds rises up, being always prayerful as difficult as it is - A multitude of things.
What I am trying to state is that they come often from things that you do not suppose, from areas that seem to pertain differently. Reading and listening to these great living dead, the puritans as they are some times called had a great demand about them, they draw things out of us, they pull at the conscience and the conviction, they challenge the perceptions, it all depends on our absorption and propensity, willingness to hear not merely listen but to allow these things deep down into our being.
Brother, I would warn against too much navel gazing as it was admonished to me by this very same wonderful crowd over the years. You can get many things up in your head and strive to preform them, promise yourself that you will do so but it is your disposition that needs altering - I am speaking from a great deal of experience. Comparisons and contrasts will do you much good. Read\\listen to autobiographies of these great saints, there is a series by John Piper here for instance that is tremendous on that level, it gives you a perspective on what they went through and by comparison it can be very humbling.
I am running on here a bit but brother, my situation is quite a bit different than yours, I have been married now for ten years and cannot go into details, but it is somewhat opposite - The overriding factor is just [i]patience[/i] and prayer. I learned the hard way through similar reactions of regret and anger, of forcing myself (that is my opinion) and of just 'giving up' and becoming embittered, I tried everything it seemed all to no avail, pleading and pouring out my heart, a plying for sympathy though I had thought it was just being honest, I could go on and on. Do you see brother what you have in your wife? Cherish it. I take no wishes from you and praise God that you have a wife who loves the Lord, let that spur you on, on to working on your character and disposition, those very things that speak louder than words.
Be encouraged and humbled, they do go togther, far more than we might suppose.
[i]Husbands, love your wives[/i]
