The Sweetest "Office"

Zap2it has a quite good article on the unrequited love between Jim and Pam. Jenna Fisher teases with this...

"There's this whole other life that they have together that makes everything very complicated for Pam," she says. "I think up until she met Jim she would never have questioned being with Roy. So, her story is she had just gotten engaged, and Roy convinced her to take a job at Dunder-Mifflin so that she could save money for the wedding. So she came into meeting Jim as a newly engaged woman, and so whatever chemistry they had, she also had the joy of finally settling down with who she thought was the man of her dreams. So I think that it's only after these three years of Roy really dragging his feet and [Pam] continuing to be around a guy who they're so clearly meant to be together."
