Quarrel and fighting are inevitable in a relationship. As human being, we tend to have different opinions and view points in certain issue. Therefore, the friction or fight begins from it. It generates without anybody conscious until it explores to hurt a relationship.

Is this really inevitable?

Compromise and Open Mind are the KEYs to resolve such problem, i believe. Why can't one party to step back? Does it really so hard to do so? or it need bring up to that extent to start a fight? It is unnecessary as both parties will get hurt at the end of it. What can we expect for a relationship if the situation persistent in this manner.

I would say endurance and understand is the greatest solution. Both parties must try to understand each other. Why must we stand so firm on our foot while you know there is nothing wrong to follow your partner idea. Put down your egoism and it definitely can bring the relationship to a better stage.

Compromise and understand are easy to talk but difficult to do.

This is also part of the lifelong learning.
