NA77:
If your father is paroled, he will likely have a parole officer who will provide supervision and a lot of "do's and don'ts". Generally, offenders are either court ordered or told by the PO that they cannot have contact with victims (or minors, etc.)
If you are not listed as a victim in his case, there would not likely be any restriction on his contact with you once he is released. There is also the question of whether or not he had sex offense-specific treatment in prison;
I find myself wondering if people can change, can a successful adult relationship be built with a parent that molested you? Should i continue to void him out of my life and so on...
Offenders generally need to be in this kind of treatment to change. If he has been in treatment for offending and really integrated it, he should acknowledge what he had done to you and possibly attempt some resolution through a therapist, if YOU are willing to have some sort of relationship with him in the future.
Regardless of whether he has been in treatment, you may be interested in reading "Disclosure and Confrontation" (
http://www.malesurvivor.org/ArchivedPages/singer3.html) which may give you some direction on where to go with this. Should he wish a relationship with you, you have the right to insist that he be in sex offense-specific therapy when he gets out. Under no circumstances should you allow the old dynamics to continue from the time of the abuse.
You can contact the state parole board to give written input if you'd like. That can be to tell them what he did to you (the "disclosure" part of the above article,) and perhaps insist that they require him to be in offender treatment once he is paroled.
