A woman hanged herself on the stairs with a dressing gown cord after sleeping with her ex boyfriend at a house in Spalding.
Alina Bogdanova (28) was living with someone when she called her brother and arranged to visit him on October 25.
Miss Bogdanova’s ex, Aleksandrs Zuks, shared the brother’s house at The Hayfields and described to an inquest how they slept together after she went to his bedroom.
Mr Zuks fell asleep with Miss Bogdanova beside him – but found her the next morning apparently “standing on the stairway next to the wall”.
He said: “I started talking and asking what she was doing there and when I came closer I realised that the bottom lip was blue.”
The inquest heard that Miss Bogdanova had been unhappy because of “health problems”, but never voiced an intention to take her own life.
South Lincolnshire assistant coroner Siobhan Kelly recorded a verdict that Miss Bogdanova took her own life by hanging.
Pathologist Dr Mike Harris said alcohol consumed that night “may have been sufficient to influence her state of mind”.
Miss Bogdanova’s partner at the time, Arturas Pakalniskis, of Fen Lane, Peterborough, was sitting feet away from Mr Zuks as the story unfolded of how her life came to an end.
Mr Pakalniskis described her as being “very unhappy” about health problems, but said she wasn’t depressed.
Although he knew Mr Zuks lived at her brother’s address, he was not concerned about the visit.
Mr Pakalniskis said: “She just said that ‘I am going to see my brother’ and that was it.”
A statement from the brother, Arnis Bogdanovs, was read in which he said it had been arranged for his sister to sleep in his room.
He texted her to say “come to bed” and she replied “sleep well”. He then texted: “Who did you come to visit?” But there was no reply. The next morning he helped move her body to his room.
