A relationship can teach you a lot of things such as the importance of communication when there was actually no requirement of communication. I know, right! Been there, done that. So while it can be so much fun to have a person you can share everything with. There are certain loopholes in the entire dilemma (excuse me for calling it that).
Some relationship issues are so universal that almost every couple faces it. Kudos to that!
PS: Just don't cry.
