Alina Bogdanova, who is not said to have suffered from depression, was found dead by her 29-year-old ex boyfriend Aleksandrs Zuks (pictured above).
The 28-year-old had spent the night with Zuks, who lived with her brother in Lincolnshire.
At the time Miss Bogdanova was in a relationship with fellow Russian Arturas Pakalniskis, who lived in Peterborough.
Speaking at the inquest at South Lincolnshire Coroners Court this week, Mr Zuks described his shock when he woke up to find his former girlfriend ‘blue-lipped.
'We slept together after she came to my bedroom,’ he said.
'I fell asleep with her beside me but found her the next morning. I thought she was standing on the stairway next to the wall.
'I started talking and asking what she was doing there and when I came closer I realised that her bottom lip was blue.'
'When I came closer I realised that her bottom lip was blue.'
Partner Pakalniskis also gave evidence, claiming that she didn’t suffer from depression.
'She was very happy. She wasn’t depressed.
'I knew Mr Zuks lived at her brother’s address but I was not concerned (about her visiting the house).
'She just said that "I am going to see my brother" and that was it.'
Following the inquest, South Lincolnshire assistant coroner Siobhan Kelly recorded a verdict of suicide, confirming:
'Miss Bogdanova took her own life by hanging.'
Speaking after Tuesday’s hearing, a friend said: 'Alina was a beautiful person.
'People thought she felt guilty about cheating on Arturas which is maybe why she killed herself but we will never know.
'It is so tragic. She was so full of life.'
