A feast for the eyes!

I am beautiful or so I am often told by others. I am alone, and I don't know why. I understand that beauty is only skin-deep, which is why I have strived all my life to be someone who is compassionate, caring, intelligent, and a good friend and family member. It's always that I get into relationships. It's love at first sight for them. They worship me and then I fall for them. Then they lose interest.What gets me down is the fact that the only person I ever really loved left me, and will probably never come back. What good is all of this if I am all alone??
