Mohammed Anwaar, 27, pleaded guilty to coercive and controlling behaviour.
Legislation to make this type of behaviour a criminal offence was only introduced in December. Anwaar, of Charlotte Road, Sheffield, also admitted nine counts of assault and criminal damage.
South Yorkshire Police said Anwaar had exercised "controlling and abusive behaviour over his partner" for about two years, beginning in May 2014.
Det Con Ian Chamberlain said: "He told her what clothes to wear, when she could see her friends and family and made sure he was with her at all times."
