I have been hoping for a long time that these feelings would go away, but they have not. I want, I could talk about it more easily with her, but right now it seems crazy to throw away what we have for something so unclear. The problem is that the feeling is a very strong one. What you have described is not craziness but emotional ambivalence. The problem is that you are not talking with your girlfriend about your true feelings.
Communication is an amazingly powerful tool.
Like any other powerful tool, it may feel risky to wield. It must be done with great care for yourself and for the person with whom you disclose your innermost feelings. In love relationships, communication is easy as long as there are only positive, uplifting, connecting feelings between us. When difficult thoughts and emotions arise, however, the natural tendency is to withhold them in order to protect the other person as well as us. The myth is that you can destroy your connection by speaking your true thoughts and feelings.
