Is there a way to get a divorce in Maryland without having to live apart for one year?

Yes if the grounds for Divorce are based on Adultery and that Adultery is proven to the Court. Also under the Ricketts case some litigants who separated within the house,( eg. one lives in the basement with a separate entrance, kitchen etc, such that they are essentially living in two separate abodes), are able to prove valid separations and obtain their divorces.
