I known a same case too, my cousin used to make cut on his arm with Hunter Knife (its goes deep) ... for her love.
His logic was, that he do it for her.. he cried .. for hours but don't stop making scar's .. open again.... i wonder if real love cost this... then my previous 23 gf's indeed were not real love !... sigh
I wish i could frame this post. And then send you to the Clinic.
