What will happen to my husband he violated parole and he's charged with spouse abuse

If he is caught after violating parole, then he will likely go to jail. The charge of spouse abuse may be a separate issue. Are you the spouse? If so, you should call the officer who took the charge to confirm what happens next regarding that charge.

He is required to tell his PO of the new charge ( most likely the police department already did that) He will be held without bond pending a parole hearing where they will decide to send him back to prison or not, and if back to prison for how long ( up to the end of his sentence)

He will then also face new charges for the spouse abuse. Parole may hold him pending the outcome of that case to decide on his parole issues.
