I have a crush on my best guy friend. He says he's in love with his cousin. He said they almost kissed and they were rubbing each others stuff. But I really like this guy and he says he realized it waas wrong and stopped and said oh sh*t but I really really like him and I wanted to be in his cousins spot.

There are lots of guys out there,he is not the only one you will ever like,also its not natural for him to love his cousin in that way and he will probably get over it,also tell him how you feel about him.
