Joey & Pacey's Relationship Was An Absolute Train Wreck
From the moment they stepped off that boat and were back in Capeside, it was one fight after another (usually centered around Joey being obsessed with Dawson and Pacey being an emotionally fragile and insecure child) and nothing but lies. The blow up at the prom was inevitable, frankly I'm surprised it didn't happen sooner.
Why do people fawn over this debacle of a 'relationship'? Comparing it to Dawson and Gretchen- a mature relationship built on trust and honesty... It's even more glaring just how much they didn't work as a couple. I guess the courtship stage was fun but the rest of it was pure dysfunction. I mean Joey couldn't find her boyfriend during a pregnancy scare because he was arrested for public intoxication and lied to her about it, as she had lied about them having slept together. Come on now...
Personally I don't see how their problems would be magically resolved following them being awkwardly forced together in the finale. Pacey would still have massive insecurity issues seeing as how Joey is an accomplished writer and graduate of the prestigious Worthington University (an education funded by Dawson) and Pacey is what... A busboy in a restaurant maybe? Not much you can do in NYC with just a High School diploma.
And worst yet, Joey seems to spend all her free time watching her childhood with Dawson play out on screen in perpetuity. She's still very obsessed with her soulmate. And once Dawson inevitably finds a new girl to obsess over now that he's rich, famous, and successful... Joey will automatically go into jealousy mode (like she did when Dawson stopped obsessing over her and looked to Jen, Gretchen, etc).
I honestly don't see that being the recipe for a long-lasting, meaningful relationship. But maybe that's just me.
