Well with all the scienc shit aside, love is real. Ulrich, don't get upset when I say this, but I think you have loved someone, but u got your heart broken. Thats why I think you don't believe in love along with other circumstances. This is friend to friend, bud. I wish I could help you realize this, but theres not much I can say. I'll just leave with this comment. Love finds you, no matter how strong of a loner you think you are and when you refuse love, it will continue to bug you until you realize how much of an important feeling it is. Maybe no one has ever shown you love before, but one day someone will.
