Marrying Lindsay had been one of the biggest mistakes of Dean's life. He knew this. The whole town knew this. At least, they did after the divorce.
When Dean had married Lindsay, he had still been in love with you... but he tried to convince himself that he wasn't since you were with another guy. He was only 19 when he married her. Young, dumb, and afraid of being alone.
But... when you had broken up with your boyfriend... Dean had been the one to console you. To hold you. Lindsay had been out that night with friends anyway. She never seemed to spend her free time with Dean. And... by accident... you two kissed. But the second you realized how wrong it was, you both pulled back, feeling guilty and stupid.
But, Lindsay found out anyway. Dean wanted out of the marriage he had made the mistake of having. So? That led to a messy divorce... and you and Dean quickly getting together afterward, after years of being in love with one another without admitting it. Or it was just always the wrong timing. Now? It wasn't.
But, nothing in Stars Hollow goes without gossip... and a mention in the town meeting. And this time around, Doose decided to mention the 'unethical' circumstances of your relationship. He kept going on and on about how it wouldn't work and was bad for the towns image.
So? You finally just stormed out in the middle of the meeting, making a scene as you slammed the door of the dance hall behind you... the cold night air pressing against your face as Dean quickly followed you out...
