Here's my two cents.

I never said one negative word about you. Really, I don't dislike you and it makes me sad that you dislike me. I never called you pathetic, and I never did anything intentional to hurt you. I don't think we've ever had a face to face conversation before, and I really am sorry if you think I'm a bitch. I never tried to get in your business about anything and I'm sorry I said anything to begin with. This is dumb and there is no reason this should be happening. So, take this as my sincere apology.
