This had probably been said countless times on this sub, but Doug and Carrie should've been divorced

Honestly a divorce would've been the best thing that happened to them, especially the direction their marriage was going in the later seasons. Up until the finale, they didn't have kids, a divorce would've been easy because they'd never have to see each other again. Doug is comfortable with being mediocre while Carrie wants to try new things, that was a sign that they are not a good match. If Doug wanted to stay mediocre, then he shouldn't have married a woman like Carrie. If Carrie wanted to explore the world, and fulfill her dream of moving to Manhattan, then she shouldn't have married a man like Doug.
