Mark Williamson sent texts to his former partner threatening to harm her and rape a third party when their on-off relationship was “messing with his head”.
Williamson (32), of Westwood Drive, Bourne, pleaded guilty to pursuing a course of conduct amounting to the harassment of Joanna Hirst by sending threatening texts on April 20.
Marie Stace, prosecuting, told Spalding magistrates on Thursday that Williamson owned up when arrested.
When interviewed, he told police: “Yes, I did threaten her. I didn’t mean it, you know, I was just drunk and being stupid.
“I threatened her because I wanted to hurt her at that moment in time. I wish I had never done it but I can’t take it back.”
Magistrates adjourned sentence to May 31 for a probation report and gave Williamson bail with conditions including one of non-contact with Ms Hirst.
Solicitor Rachel Stevens, mitigating, said for three years Williamson had been very much in love with Ms Hirst, they had lived together and they were engaged. He was drunk when he sent the texts and was later “pretty mortified” by the content.
