I wonder why things had to change between us. We were as close as siblings, a sincere bond from the beginning. I never craved for anything more than your friendship, but recently it seemed too big of a burden. I never intended to steal your attention away from him. Maybe I just wished you were there for me as I have sincerely been there for you.
Do you remember you once said "I don't like the person that you are when you're with her"? Now I know exactly what you meant. I realize that this might be the price we have to pay for being good friends with the opposite sex. Understand that I mean you no offence. I wish you the best if things will never be the same again.
