It was Pacey's insecurity that originally broke them up in the Prom though, there was every indication that Joey was still happy in the relationship up until then. Joey spend three months at sea with Pacey, and almost an entire school year in a relationship after that, with no sign that she felt something was missing and she needed to "find herself". She was still all over him and very much in love just a few episodes before the Prom break-up. And she was again all over him in their season 6 reunion, at least until she want back to a high school Prom with him, which brought back all of those memories which Joey admitted to running away from in the finale. I think that they would have had a shot at making it work after the finale as I never doubted that they were deeply in love when they got past their insecurity issues. And considering that Pacey actually seemed genuinally excited at their calling Dawson to congratulate him in the final scene, I got the sense things were more stable for them by then.
When they weren't arguing over Dawson, they actually were pretty happy with one another for most of season 4, and I never saw any sign that Joey regretted picking Pacey, or still saw Dawson as a viable romantic option. It was really Coda that pushed that on the audience out of the blue, seasons 3 and 4 had all been about Joey outgrowing Dawson and realising her romantic feelings for him were in the past, but still wanting to hang to their childhood friendship. And with seasons 5 and 6, it could easily be argued that she was only kissing Dawson again after Pacey broke her heart and he was the safer option. Even Dawson called her on the fact that she was always pretty half-hearted about an actual relationship with him, and coming up with reasons not to truly commit. Really her rushing into kissing Dawson right after she and Pacey split up, and she spend time reminiscing over her happy childhood with Dawson, just points to her using Dawson as the safe option that she could use to run away from/downplay her feelings for Pacey
