Whether or not you voluntarily or otherwise tell your son's mother where you are living will not resolve this problem. The situation clearly needs to be put in order for everybody's sake. If your son is to live with you it would probably be appropriate for you to obtain a residence order in order to regularise the position.
You need also to give very careful thought to what is in your son's best interest. Is it really in his best interest that he should not be allowed contact with his mother? Should you not put his fears at rest and assure him that you will protect him if he has contact.
