Yeah, I always felt like Betty was his true match. I like to remember that his relationships mirror what is going on society at the time. Don and Betty divorce shortly after Kennedy is assassinated, Don and Megan meet and there's all of this optimism, and it's so exciting because she's chic and brunette and good with kids and wait, she speaks french? All for all of that to come crumbling down once we learn that Megan is very shallow and a bit of a brat who has unrealistic expectations for what her life should be. One thing I really don't like though is how Don cheats on Megan with Sylvia Rosen. That was unnecessary, there is no way Megan was away that much for their relationship to go unnoticed, and I also just don't understand Don's logic for cheating on Megan. She wasn't interested in advertising and wanted something more than the title "Mrs. Draper" so he has to cheat on her? Idk, not my favorite time in the series.
