^She could have easily told Lindsey about the kiss if she really wanted to be "pathetic". As insecure as Lindsey was, Peyton had plenty of options if she really wanted to prevent Lucas from marrying Lindsey.
The only reason Peyton didn't tell Lindsey is because she isn't stupid. She wanted Luke, but being vindictive would not have gotten him. It would've cause a rift between LL but it would not have gotten her what she wanted. If she had done that, she would've only pushed Luke away more. I mean Luke already treated her horribly when it wasn't her fault, could you imagine if it was?
And I don't think Peyton bowed out gracefully, if she had she wouldn't have begged Luke not to marry Lindsey. They only reason she didn't do any worse is because she had realized that she lost. And she did lose because the only reason he didn't marry Lindsey was because Lindsey
said no. He had already said I do.
