The 21-year-old Sullinger appeared in Waltham District Court on Monday to face charges of assault and battery, destruction of property and witness intimidation in connection with the Aug. 31 confrontation with his girlfriend. She accused Sullinger of pinning her to a bed and the floor at his Waltham home.
His lawyer, Charles Rankin, says the girlfriend does not want to continue the case and is not afraid of Sullinger.
A spokeswoman for the Middlesex district attorney's office says prosecutors "believe we have evidence to support the charges.''
Sullinger has pleaded not guilty and remains free on $5,000 bail. He called the charges "embarrassing.''
