"I'm here for you", that's what you said.
"I always help you", that's what you said.
"I appreciate your help", that's what you said.
"I don't love you back", that's what you said.
"You're a selfish *******", that's what you meant.

It's scary how words can leave a more devastating result than any given weapon.
