Claudia Williams’s mother said ‘happy is not the right word’ after Richard Bromley was convicted of causing her daughter’s death by careless driving.
Andrea Williams said she was more ‘relieved that justice has been done’.
It is more than 1,000 days since the crash which took Claudia’s life on June 24, 2013.
Her mum said: “The past two years and 11 months have been absolutely devastating and very difficult for myself, my family and friends of Claudia.
“I feel relieved that justice has been done, but happy is not the right word to use by any means, as we will never get Claudia back.
“I hope that Rick learns from this, and other people both young or old.
“This is also a very hard time for Rick and his family, and when this is all over for him, I hope he can move on with his life.”
Bromley, of Daniell Way, Great Boughton, was found guilty of causing death by careless driving by a majority verdict of 10 to one.
He was at the wheel when his Vauxhall Corsa left School Lane in Guilden Sutton and collided with a tree.
Claudia, who was in the passenger seat, passed away from her injuries.
They had been a couple for about a year and were on the way home from a meal with her family at The Old Trooper pub in Christleton.
Bromley, now 23, admitted drinking three and a half pints of lager at the pub between 6pm and 9pm; the crash happened at about 9.40pm.
But he said it was caused by his girlfriend shoving his left arm during an argument, which caused the car to veer off the road.
During his evidence he said he would do ‘anything’ to change the events of that night.
Claudia, from Hoole, had been a student at West Cheshire College and was a former pupil at Christleton High School.
As a youngster, she had been a member of Saltney Gymnastics Club and represented Wales.
Judge Neil Flewitt QC praised both families for the ‘dignified’ way they had conducted themselves throughout the three-week trial at Warrington Crown Court which came to an end on Friday (May 27).
Bromley was cleared of a more serious charge of causing death by careless driving while under the influence of drink or drugs.
He is due to be sentenced on June 28. Judge Flewitt told the 23-year-old there was a ‘very real possibility’ he could be sent to custody.
