Do you feel that you have never felt love, and you are just putting on a show of being in love? If you can't let love in, then there might be something buried deep in your mind. Whenever someone approaches you, you hide in a shell, pretending that you are not interested in love at all. You think: "I can't fall in love because it's just a silly thing." Shutting your emotions like that can lead to loneliness and even depression or anxiety. Whether you do this because of a troubled childhood or an abusive past relationship, it will keep on affecting your relationships. That's why consider the underlying issues before saying: "I can't fall in love."
