This is a major thing in relationships, because a relationship is full of sacrifices everyday, dealing with many different things. When you decide to get into a relationship you are making a commitment; therefore, you have to make the sacrifice of some desires or attractions to other women/ men
or even things. There are some people who tend to disregard this like the man in “Popular Mechanics”. He did not put others before himself and in turn hurt his significant other so bad causing her to yell “I’m glad you're leaving!”. But what changed everything was their baby they had together. She had also put her wants over what was more important, that baby. She was so mad at him, she wanted to keep the baby so bad she forgot about the safety and the well being of the child. This happens a lot when marriages end in divorce, the two people get so angry and fight they forget what effect this will have on a the kid. I remember the second time my dad got divorced , I was too young to remember the first, and the feeling it gave me every time they fought. I would sit in my room and cry and at points it would get so bad I would have to put in headphones to drown them out. Fortunately the age of this baby is an advantage because he will not remember this altercation. But what is sad is that the parents were so involved in their problems that they were willing to pull at this baby’s arms and physically hurt him. Until they had that glimmer of realization as they were hurting him that they needed to stop because stopping meant doing what's best for that baby’s well being.
This is not the most important thing in life, but it will take you a long way when you realize some things are just for the best. Putting certain things before yourself can save a friendship, relationship or just be in the best interest for another's well being. So you should always try to put others before yourself in an important situation, such as a kid during a divorce, so that you do not end up tearing them or you guys apart
