A man with three girlfriends got into trouble with the law when he started drinking.
John Butler first moved to Blackpool when he met a woman, who lived in the town, on an Internet dating site.
He then acquired another two girlfriends but was arrested after assaulting both of them.
Butler, 28, of Peter Street, Blackpool, pleaded guilty to affray, two offences of assault and two of damage.
He was remanded in custody to appear at Preston Crown Court on November 26 by Blackpool magistrates.
Pam Smith, prosecuting, said that on November 2 Butler argued with his ex-partner, grabbed her by the throat and pushed her.
At the climax of the row Butler’s girlfriend turned up and he grabbed her clothing near her neck.
Butler threatened to burn his ex’s house down and came out of her address with two knives. When interviewed he told police: “I am going to prison.”
Alan Godwin, defending, said Butler came to Blackpool after meeting a woman via an internet dating agency.
Butler’s first girlfriend had offered to let him live with her if he was allowed bail. Since coming to the resort he had been involved with three women. The second and third girlfriends wanted nothing to do with him.
On the day of the offences he had been drinking heavily.
