How realistic is it for someone to be "just friends" with their ex?
Being "in love" is a wonderful experience. People tend to fight this "natural feeling" instead of embracing it because they think it's a sign of emotional weakness. However, we all experience love at some point in our lives, but very few of us can say they are honestly "in love."
Long distance relationships really can work. It takes some effort and creativity, but don't give up on the person you love because of a few miles.
