Kitti Jones -- one of R. Kelly's exes who accused him of physical abuse and sexual coercion -- says there's only 2 ways he can fix himself ... taking accountability and serious therapy.
Kitti says R. Kelly needs to accept the harm he's inflicted on his victims and turn his life over to God ... plus making the most of the mental health treatment he's been ordered to undergo upon his prison release.
As we reported ... Kelly was recently sentenced to 30 years in federal prison following his conviction for 9 federal charges, including sex crimes and human trafficking.
Kitti, who appeared in both 'Surviving R. Kelly' docs and gave a victim impact statement in front of Kelly at his sentencing, says she's happy Kelly is off the streets so he can't hurt more women.
For Kitti, Kelly's conviction is giving her some closure ... she tells us why she doesn't think he will pose much of a threat whenever he's released from prison, regardless of any changes he makes in federal lockup.
