A woman who stabbed her son to death following a mental breakdown brought on by her bullying airline pilot boyfriend has described him as a "controlling monster".
On Thursday, Peter Chilvers, 33, was jailed for 18 months after he was convicted of controlling and coercive behaviour against Magda Lesicka who he met when they worked at Ryanair .
Last July, Polish national Lesicka, also 33, was jailed for 15 years after she stabbed to death their 23-month-old son James at her home in August 2017.
Her sentencing hearing was told she was subjected to relentless psychological torment from the flight captain during their toxic relationship.
The couple had been together since 2010 but Chilvers cheated on Lesicka from 2014 with another Ryanair cabin crew member, Lisa Spencer, who is now his partner and mother to his two young daughters.
Chilvers had repeatedly threatened to kill Lesicka if she removed their son from his care and demanded they continue to live together at a new home he bought in the Cheshire village of Wincham.
Lesicka admitted manslaughter by reason of diminished responsibility on the basis her mental illness emerged without warning, and she had no memory of committing the offence.
She went on give evidence in the prosecution of Chilvers at Manchester Crown Court and parts of her victim personal statement composed in prison were read out at his sentencing.
The former flight attendant said the statement was "a closing chapter on the most horrific experience I have ever had and now I only have my flawed memory to work out how it got to this point.
"It's hard to see myself as a victim given the tragic outcome. I know my life has been changed forever and there is nothing I can do change it back.
"I have the rest of my life to contemplate these events and it is a daunting prospect.
"When I started a relationship with Peter Chilvers I had absolutely no idea he would be the controlling monster I discovered him to be.
"It is important that the public understand what Peter Chilvers's abuse did to me. It destroyed me. I have no idea how he achieved this and I will probably spend the rest of my life trying to work out how he turned the confident ambitious me into what I am now."
She went on: "I have very little left in my life, not even my freedom. This is my burden to carry. I accept it in the hope that some day I can move forward. I was broken by him and I can never be the person I was before I met him. I am alone now, I feel ugly, worthless, defenceless, ashamed, guilty and weak.
"Peter was responsible for doing what he did to me. I am genuinely terrified he will do this to someone else."
His controlling or coercive behaviour between December 2015 and August 2017 included using or threatening physical violence, forcing her into degrading sexual acts and isolating her from her friends
Chilvers, of Hewitt Grove, who has no previous convictions or cautions, was cleared last month by the jury of two allegations of rape and one count of assault by penetration.
Reporting restrictions on the case were lifted as the court heard that Lesicka had "unequivocally" waived her anonymity as a sexual offence complainant in her victim personal statement.
Sentencing, Judge Patrick Field QC said he was satisfied that part of Chilvers's controlling behaviour was sexual.
He told him: "Whilst I accept that the jury acquitted you of the more serious sexual offences, it is undoubtedly the case that throughout the relevant period, particularly when you and Magdalena Lesicka were not sharing a bed, you continued to treat her as your sexual property.
"To use her words, you would help yourself to her body and she would consent because she felt that she had to whatever was required of her. Such was your control that she felt she had to put up with it.
"Throughout the period with which this indictment is concerned your behaviour towards Magdalena Lesicka was that of a selfish, entitled bully. I have detected no more than a hint of your remorse."
Mark Ford QC, defending, said character references for Chilvers provided to the court painted a "very different picture" to that given by Lesicka.
He said that Spencer had attested to a supportive, co-operative and loving relationship with Chilvers.
The defending QC said Chilvers was the sole carer for their two young daughters while Spencer was out at work and that immediate custody would be a "significant threat" to his mental health.
Arguing for a suspended sentence, he said: "In short, he is a man on the edge. Just a few years ago Peter Chilvers had the world at his feet. Now he faces the difficult and, if I may say so, painful challenge of rebuilding his life."
Outside court, Detective Chief Inspector Richard Eales, of Greater Manchester Police , said: "If people take anything away from this heartbreaking case, please let it be that there is support and help available for those who are suffering at the hands of domestic abuse.
"Most importantly though, I hope today's result has seen justice served for the person who matters most - James."
Ryanair pilot Peter Chilvers and flight attendant Magda Lesicka appeared to enjoy a perfect lifestyle as they travelled the world with their son James.
But all was not well under the surface as Chilvers had already cheated with two women before James was born in September 2015.
The pair met at a party in 2010 when both were based out of a German airport.
A month later they kissed at the staff Christmas party and started a relationship, moving in together.
Chilvers later transferred to Liverpool Airport and Polish national Lesicka joined him, only to become isolated.
Her social life suffered after she became financially dependent on the pilot.
At his trial at Manchester Crown Court, in which he was convicted of controlling and coercive behaviour, prosecutor Rob Hall said Chilvers started to dictate to Lesicka who she saw and when she went out.
Mr Hall said: "Over the months and years that followed, Peter Chilvers repeatedly mistreated and bullied Magda Lesicka at ever increasing levels to see what he could get away with.
"Ultimately, Peter Chilvers treated Magda Lesicka as if she was a possession to do with as he pleased."
In May 2014, Lesicka got a job working as a retail service manager for Cross Country Trains, based at Manchester's Piccadilly station, after the couple moved to Lymm, Cheshire.
Their difficulties were compounded as Chilvers embarked on two affairs, including one with Ryanair cabin crew colleague Lisa Spencer.
Lesicka moved out at the end of the year when she found out about one of the affairs but then learned she had fallen pregnant after her contraceptive pill failed to work because of an infection.
In April 2015 she discovered that Chilvers was having an affair with Ms Spencer.
Chilvers promised Lesicka he would stop seeing Ms Spencer but told the jury he was "weak" and, unbeknown to Lesicka, was drawn back to the other woman.
Soon after James's birth the couple moved to Lanzarote when Chilvers was promoted to captain.
Lesicka again found herself isolated and financially restricted on the Spanish holiday island, the court heard.
In 2016 she discovered the pilot was still cheating on her with Ms Spencer and suggested she and James should leave Lanzarote for the UK.
Mr Hall said: "Peter Chilvers responded with words to the effect of, 'If you ever try and run away and hide, I will find you and will kill you'.
"Thereafter, this type of threat became a regular occurrence and was randomly issued by him without any real reason or cause."
In August 2016, Lesicka moved with James to Wythenshawe and Chilvers joined her in 2017 when he started flying in and out of Manchester Airport.
In July 2017, she discovered she was pregnant again but could not cope with being trapped in an "abusive, humiliating and dishonest relationship", said Mr Hall.
On August 15 she had an abortion without Chilvers' knowledge, and told him two days later.
In the days leading up to killing James - after suffering a mental breakdown triggered by Chilvers campaign of bullying - she desperately sought help to escape the toxic relationship by contacting the police and domestic violence charities.
