The ex-England footballer, who is currently at the Priory rehab clinic, is reportedly "haunted" by his violent behaviour towards Sheryl in their two-year relationship.
Sheryl, 42, has been regularly visiting the troubled star during his latest effort to deal with drug and alcohol addictions.
"Sheryl is 100% Paul's rock - she has promised she will not leave his side now and is going to be there for him every step of the way," a source told The Mirror.
"They have been divorced for ten years and have this week spoken at length about how Paul mistreated Sheryl.
"He told her he would never raise a hand to her now and is so, so sorry for what he did to her.
"Sheryl has forgiven Paul but he is still haunted by the violence. It's what began his demise into drink and drugs."
