Hate Me by dreamingkate
Whenever Kurt wants to shut down a disagreement or argument, he throws the cheating incident in Blaine's face. He is unaware how much this hurts his fiance and how the incident still deeply affects him to this day. Kurt's heart breaks when he overhears Blaine saying affirmations to convince himself he's not horrible person.
Wow! This is one angsty story! The emotions portrayed by both characters are so palpable that my heart literally hurt for Blaine and his feelings of self-loathing brought about by the person he loves most. I would definitely recommend this short story. It will tug at your heartstrings.
