I recently found out from our nanny cam that my ex covert narc husband was planning to sexually abuse girls at a sex party by spiking drinks and putting marijuana in his birthday cake. I divorced him because of adultery, emotional abuse and substance abuse. After separation, i kept supervising his visits with our 4 yr old daughter and 3 year old son but during one of his supervised visits I popped downstairs & overheard him on nanny cam having phone sex on some group sex chat forum with my daughter alone in the room and he left my son unattended in the living room. I confronted him and he tried to minimise and avoid. Since then i noticed some perverted behaviour towards my daughter. Last visit she was hitting his hand when he was trying to buckle her in her car seat and telling me mummy no. She has speech delay so as you can imagine she is more vulnerable. Now He has gone behind my back to apply for unsupervised visitation. I’m so distressed. I’ve gone no contact and he has to go to court to get an order to see them. I’m so worried. Not sure what he can apply for or what i can do to keep visitation supervised or get full custody? I’ll be grateful for any advice or similar experience? Thank you
