Don't forget, the extremely happy times in a relationship makes up for the bad times. If you love someone so much, maintaining the relationship should not be an issue at all. Time passes by very QUICKLY, and only time can reflect whether the couples are meant to be for each other. I don't believe it's really "effort" or hardwork to maintain a relationship if you really love her/him. Also, "loyalty" is not really the question if he/she loves their significant deeply. He/she will never want to hurt their lovers, but if they ever decides to; then I believe the relationship doesn't deserve to be maintained. As humans and lovers, we learn more about the love concepts and the feelings associated with love with the significant other. In my opinon, love is always something that one should give his/hers everything in order to see quality or improvement. We always have to risk most things if not all if we love someone. Therefore, maintaining a relationship is just one of the natural act that one must take on, but at the end, it probably is worth it.
