In the beginning of November I was cooking dinner when my 12 year old son came downstairs and told me that my 15 year old son and my 10 year old daughter was doing something funny. I looked at him and said funny how? Like sexually! I called my other 2 children down still cooking dinner trying to keep collecting I said someone needs to start talking and now. My 15 year old son (who has Autism Spectrum Disorders (ASD), adhd, ptsd and impulse control) told me that he and his sister had been doing sexual acts for 5 years! So at this point I feel it is necessary to give you some background. I had only had full custody of my children for 2 1/2 years. I left my ex husband in 2011. My ex husband was abusive and I had suspected at that time of him sexually molesting my daughter. He was on drugs and erratic. I left him a few times before but was always talked into coming back. So I took the kids with me to my father's which was out of state but the safest place to be. When I got to my father's I immediately got a restraining order for the kids and I. Long story short the court gave him custody. I never stopped fighting for my kids. After a horrible abuse incident involving his step son I got full custody of my kids via a CHIPS petition. Since I have had custody my kids have been in weekly individual therapy. My 2 boys also have had mental health socail workers. No one saw any evidence my son molesting my daughter. My daughter did show signs of being molested but I believed it was due to my ex. I have full transparency with the counselors and social workers because all I wanted to do was help my kids. After finding out that my son had been molesting my daughter I called my therapist who is my daughter's therapist as well. She told me that I needed to call the police and getting my daughter checked out. So I called the police and told them to meet me at the hospital. My son was taken into custody that day. He is currently in a residential treatment facility for sexual issues. My issue is that the treatment facility keeps talking about reunification. I have major issues with this. I don't believe I could have done anything more to prevent this from happening. My children were never left alone. I haven't dated in a long time totally focusing on the kids. I never left them home alone. My therapist wants me to come up with stipulations or things my son needs to work on for reunification. Any ideas on what I could do to guarantee the safety of my daughter with my son living in the same house?
