Hello. I am sorry for your misery at this time. The first thing that comes to my mind is stay SAFE. How old are your children, some molestors never change, even at old age. Please do not take your childrens lives for granted. If for one second you feel threatened move, or have then move, and let an aide take care of this person. You owe it to yourself and your family to have something to give to someone else. I frankly feel that you ahould have someone else look after this person, and stay safe. Period. Only because it sounds as if it is causing you a lot of pain and confusion, and you do not have to feel like you have to be unsafe. There are aides that can take care of people, and help keep the family structure in tact. Be wise and be safe, if you have a Dr and therapist ask them how they feel that you should handle this situation, your mental health is priceless, and it is not fair to you to have your mental health damaged in this manner, by anyone. It is okay to get help that is needed, to preserve your integrity, and family. Take care I really hope the best for you in this situation. Sincerely Soidhonia.
