Here is a basic and practical article about how to end disagreements. There are only about 3 ways it can go. Gary Chapman explains a simple formula.

Three Ways to Make a Decision When You Disagree
 
By Dr. Gary Chapman
 
There are three ways to make a decision when the two of you don't agree.  
 
1. Compromise
 
After hearing each others' ideas and desires you may decide to meet each other in the middle. That is, you each give up something in order to reach a solution.  
 
2. Accept Disagreement
 
Second, you might agree to disagree. Since we can't agree, we just give each other the freedom to do it their way. This works well with the toothpaste battle. You get two tubes, and let one be a middle squeezer and the other a bottom squeezer.  
 
3. One Goes Along With The Other
 
The third possibility is for one of you to say, "I think that this time, I should do what you're asking. I see how important it is to you and I'm willing to do it cheerfully."  
 
Each of the above three solutions requires understanding, loving attitudes, and a willingness to change.
 
Here are some wise words from the Apostle Paul, "Do nothing out of selfish ambition or vain conceit, but in humility consider others better than yourselves. Each of you should look not only to your own interests, but also to the interests of others." 
 
Put that concept into your marriage and you will be well on the road to success. Two selfish people will never have a good marriage.
 
Two people who are looking out for the well-being of each other, will find harmony. Decisions will not end in a battle if your attitude is "What would be best for you?" Of course, if this is always one-sided, where one side does all the giving, it will lead to resentment. 
 
Mutual respect and mutual love are the keys to a successful marriage.
