People often believe that when you go into a relationship it will be perfect. NO fighting, No tears, and NO worries. In reality there will be tears, there will be fighting and you will worry. It is because we are human. No real relationship will ever be perfect, perfect is boring. We all have had good and bad relationships. It is the ones that you care for the most that you will fight for.
We sacrifice a lot while in relationships. Time, energy and personal space is lost when you are in a relationship. With all of the sacrifices, you still gain a lot from a relationship. Trust, loyalty and honesty. How to care for someone else besides yourself, and how to love someone and open your heart up to someone else.
I believe if you really want the person you are dating and are willing to make sacrifices and be willing to open your heart up to that person, then fight for that relationship, enjoy that relationship.
