From what you are saying, you never filed a paternity action to determine custody and parent-time. ORS does not do that.
Your best bet is to file such an action, have a reunification plan ordered by the court and then see how dad complies and if things work out. That is the best bet for protecting your son, while safely learning if dad can be around your son.
Hire an experienced family law attorney to assist you on this.
