Reid was given the £2,500 ring by the former glamour model on the eve of their Las Vegas wedding last year.
Price, who announced the end of her 11-month union to Reid last month, flew out to Los Angeles yesterday, apparently warning Reid not to have any parties in her Surrey mansion while she is away.
"Although the divorce is pressing ahead, Alex still wore his ring around the house and she never complained," a source told The Sun. "She has been leading him on for several weeks now - that is why he hasn't left the house. She told him she needs him there as her bodyguard.
"But yet again she has jetted off around the world and discarded him like a used tissue."
They added: "He understands that he needs to take off the ring to move on, which he has now done. He's in pieces about it."
Price has reportedly taken her son Harvey to LA with her, while Peter Andre has taken their children Junior and Princess on holiday.
