And once you love, it's important to be giving. Giving means that you care and can demonstrate active concern for the other person's life and growth. The second way of giving is to be responsible and respond to the emotional needs of another. The third way is respect which means seeing the uniqueness of a person and wanting them to grow and be fulfilled. But in order to care for, respond to, and respect another you have to really know the other person.
One of the things that's hard to take is when someone mistreats you while telling you that they love you. But love isn't about words, it's about deeds and is a behavior. To me that means that you not only have to say "I love you" but you have to show it.
