Dexter is single, but has dated both Ki and Sharon in the past. He tended to be smothering and possessive in both relationships. Ki breaks up with him after he redecorates her office against her will, and Sharon breaks up with him some time between Fooker's trial and Fooker calling her on the run. Since then he has mellowed out, but he has very little social luck. He originally hated Nick because Nick has been condescending of him in the past. Still, Dexter helped Nick save some stranded children during a major flood at his request, then pulled Nick from the flood when he nearly drowned, allowing Ki to give him CPR and save his life. Since Dexter permanently joined GPF Software, he and Nick appear to have made up; Nick explains that he had been cast as a villain in his comic books because they weren't friends at the time. Despite initially being offended at how he was cast, Dexter is interested in finding out how evil his character was.
