Is it possible to reconcile with someone who insists on rewriting the script?

Without going into all the gory details, my husband is currently estranged from one of his grown children. About six months ago the boy got angry for something that literally had nothing to do with his father and has refused to speak to him since. DH isn’t interested in writing off his son for good, and every time he attempts to engage him to try to resolve the issue, his son rewrites the script and invents some new wrong his father perpetrated in this situation. Does anyone have experience with situation such as this? Any ideas of what might work to begin the process of reconciliation?
