If you're into it from a historical and not just the early-church revision stuff? It would have been very, very, VERY odd for a 30-something Jewish man to be unmarried at that point in time. Indeed, at any point until fairly recently. Judaism is built around the home and family life. The early church did a lot of fancy footwork, trying to mold him into something he didn't necessarily present himself as; I believe very much in Jesus as a Jew with radical ideas, who lived his life according to halacha at the time. Which would in all likelyhood have included marriage. Mary Magdalene is the only woman we see with a special connection to him, so I'd say she was as likely to be his wife as not.
