AN: Inspired by lyrics from "Who's David" by Busted. Not sure what episode this was but it is season two - after Finn finds out Rachel made out with Puck. Just a little bit of Finn's thought process.
"I never thought you would make me feel this way," I told her, before turning my back on Rachel Berry and walking away. As much as I loved her, this was unforgivable.
She had made out with Puck! Anything sympathy I'd had for her about how she had found out about my past fling with Santana, while I wasn't dating her, was squashed with that admission. I hadn't done that while we were together. I had never cheated on her - on either of them. What was it about me that made my girlfriends want to 'get it on' with Puck.
Maybe Kurt had the right idea. I doubted another guy would get jealous over who you had hooked up with when you hadn't even been dating them. Another guy wouldn't think that making out with your best friend during an argument would put things even. What kind of twisted world did Rachel even live in anyway.
