What upset you is That He will never have to chose between Her and You Because You are so Ugly Stupid Repulsive Annoying Pointless Worthless Unwanted Unnecessary Space waster Good for nothing Disgrace of humanity That no one would every chose you Especially not when given an option as amazing as Her
And no one half as brilliant as He is would ever look at you twice
Him being nice to you means nothing - he is a kind person You being there for Him means nothing - you were the only one online Her being with Him means everything - he really likes her
So what upset you? The fact that you're not worth so much as knowing your name, let alone choosing over someone else.
