I'm in love with my cousin... how can I fall out of love?

You sound like a very nice and respectable person, and I really do not think what's happened here is bad. In ancient and colonial times, cousins married all the time, so this is not anything new and was once the norm. The problem is we live in a world today that is sex crazy. I always believe that one must do whatever they feel they must in order to fulfill their happiness in this life; otherwise, they will not live life to its fullest. If you feel he is your one true love, then he simply is and there's nothing anyone else can do about this. If you feel that you will receive a violent reaction from your family about this, yet you love him as you say; then just keep the relationship a secret. If you love him as much as you say you do, why don't you see if you could work out something where you stayed with them and went to college where the cousin is currently living since they are family, but I wouldn't let my family know since I'd already know what their reaction would be to this. I hope this has helped you and best of luck to you.
