Any relationship takes work. Individuals are so complex, and communication is difficult between any two people. Add the tension of a romantic connection, the pressure of the communication -needing- to work, and its even harder. You become so invested in the other person, and in some people's cases, you actually merge with that person, so little misunderstandings or disagreements seem a lot bigger than they would with a person whos just a friend. Its normal. Some people just let these little issues fester, and thats not healthy. Many don't care to fix it, or they feel hopeless about fixing it. I think counseling is a positive thing assuming you find a counselor whos not an idiot. I saw one with my college bf, and the things that I learned help me to this very day. I did end up breaking up with him, but I should have known we were over long before we went to see a counselor. Actually our first date should have been the last one.
Anyway, I really did learn some valuable things that equipped me to get through a lot of issues with people later in life.
