I think it's important to figure out if these feelings are a result of being apart (lack of communication, or something else entirely), or if you really are ready to move on with your life and away from this relationship. Communicating some of your feelings with him might help you figure things out a bit. And you're right, it'll only hurt you both to stay in this relationship longer if you're not feeling it anymore. Maybe have a wee think to yourself about what you want in your life, where you want this relationship to go and if you can see any of this being resolved. If it's a matter of communication, distance or anything else, and if you think that can be worked on, then talk to him about it. Tell him how you're feeling. But if you feel that you've fallen out of love with him then that honestly is ok, it does happen.
