Love That is Based on Passion Can Fade
During the first months of marriage, feelings of loving and being loved are everywhere. This is because both the male and female notions of "love" are fulfilled. Youthful vigour and the absence of children make it easy to maintain a high level of physical intimacy and closeness. If these pining and passionate feelings are what we base our notion of "love" on, it's no wonder more mature couples feel that they are out-of-love. The longer you are with someone, the more difficult it becomes to maintain that initial level of passion. Children, careers and responsibilities make it more difficult to stoke the fires of passion.
