A terrified woman fled to a hotel bar when her partner woke her by screaming and shouting in her face telling her to stop moving in her sleep.
The incident, in a hotel where the couple were staying, formed part of an harassment charge against James Evans as he was jailed for a series of offences at Nottingham Crown Court.
The court was told Evans would constantly make allegations about his then girlfriend cheating and would shout at her about that.
And there were numerous arguments concerning drugs.
At one point, Evans went to prison which "gave her relief", said David Eager, prosecuting, on Tuesday, March 1.
Evans was jailed for a total of 18 months for offences of harassment, disqualified driving, criminal damage, common assault and attempting to pervert the course of justice.
The common assault was on his partner's mother at a barbecue on July 14.
Evans, 30, of Derby Road, Bramcote, was "bragging" about taking Xanax (a prescription medicine that's used to treat anxiety disorders and panic disorder).
"He wasn't really getting any attention and appeared not to be happy about that," explained Mr Eager.
"He threw a glass to the floor in the victim's direction and a piece of glass flew up and cut her face.
"It was reckless assault with a weapon. Having done that, the defendant staggered off in his drunken state making no apology for his actions".
Later that month, he drove towards his girlfriend and her mother in a van and they both had to get out of the way and sought refuge with a neighbour.
Evans was reluctant to be arrested and climbed onto the roof of a neighbouring property which caused damage to the roof.
The defendant also sent messages to the girlfriend offering her money not to call police.
The court heard, in mitigation, from barrister Sonal Ahya that "the relationship is very much over".
She said Evans offered £10,000, but her client did not have the money, to pay the victim. The attempt he made to pervert the course of justice had no effect on proceedings whatsoever.
"He has been remanded and recalled since the commission of the offence back in July," she told the court.
"When he is released, he hopes to sort his life out. He is hopeful he will find employment and hopes to move out of the location these offences were committed".
As he was sentenced for all the offences he had admitted, he was banned from driving for two years and given a five-year restraining order to stay away from the ex-girlfriend and her mum.
