to whom it may concern:

i'm sorry that i have to act that way.  believe me.. it's not my intention but somehow, i thought i have to make you feel that i really don't want to see you as i don't have enough strength on how to tell you the things i wanted to say.  i felt really bad about it.  as much as i wanted to be honest, i don't have much courage to hurt you.  just give me time to gather my thoughts and myself again.  i owe you the honesty and openness and i don't want to keep you hanging and waiting. 
i would really like to keep my friendship with you and that's only relationship i wanted to keep between us and nothing more than that.  i'm truly deeply sorry.

sincerely...
