Relationships

So this friend of mine is having problems with his girlfriend. She is still in High School and he is in his first semester of college. They have been having major issues because of the lack of communication between the two of them. They have recently broken up and he is really upset and is trying to give her some space, even if she doesnt want it. Now, dont take me wrong, I'm not sidding with her, but I'm only getting one side of the story, and I am trying to look at the situation as a whole. I have noticed that communication is few and far between with this couple and I believe that this is the main problem with them. A relationship will not survive without constant communication.
