The girl, who cannot be named for legal reasons, was only 15 when maths teacher Jeremy Forrest started a sexual relationship with her and the pair ran away to France last September.
A family source said the girl, now aged 16, claimed to still be in love with Forrest, was planning to visit him in jail and hoped to marry him when he was eventually set free, The Sun reports.
The teen's father has spoken out in support of his daughter and her relationship with Forrest, saying "I'd be proud to walk her down the aisle".
"I honestly believe he loves my daughter and she’s besotted with him. She has made it clear she wants a future with him,” the father said.
Forrest was sentenced to jail in Lewes Crown Court, in Essex, on June 21 after being found guilty of abduction and sexual offences.
The girl's father said he would like to meet Forrest and hoped he would be freed on parole after a few years.
"I'd like to visit him in prison, shake his hand and say, 'Thanks for looking after my daughter'. I would be nice to him," he said.
In court, the prosecution labelled Forrest a "paedophile" who had "groomed" the vulnerable teenager after the pair met at a school in southeast England.
Their sexual relationship began shortly after the pupil's 15th birthday, the court heard, with regular trysts in his car, in hotels and at the home he shared with his wife.
The two fled the UK on a cross-Channel ferry to Calais in France when they feared the affair was about to be exposed, leading police to launch a high-profile international search.
Police apprehended them a week later as Forrest was trying to seek work in France.
As the jury returned to deliver its verdict after a two-week trial, Forrest told the girl "I love you".
She burst into tears as the guilty verdict was announced, and told him "I'm sorry" as he was led away to the cells.
Forrest's defence lawyer had argued he felt he had to run away with the girl because he feared she would commit suicide.
