The model, 24, dumped the reality TV star over the phone, leaving him shocked by her decision.
A source revealed that Bear has been trying to get in contact with her, but she has now blocked his number.
Adding that, "He said he was beside him and cried for days when Jessica ended things and has been sending letters asking for a second chance.
He is said to have "cried for days" after she dumped him and also sent her countless letters from his cell at HMP Brixton.
Despite his conviction and sentencing, Jessica has previously vowed to remain at Bear's side “through thick and thin.”
Last month the model was seen moving out of Bear's Essex home after he was forced to sell up following his revenge porn case.
He was ordered to pay out £207,000 in damages, in one of the highest ever payouts in breach of privacy cases.
Bear shared the secret clip he recorded of Georgia with friends, ignoring her pleas to delete the video before publishing it on his Onlyfans account.
Georgia, who waived her anonymity, has become a campaigner calling for tougher measures against those who share explicit content without consent.
She told the High Court in July that the leaked video was her “worst nightmare”.
The High Court ruled Bear must pay £207,900 in damages to Ms Harrison.
