Unfortunately things have gone from bad to worse

My partner was found to have images of girls on his PC (under 50), they seem to be teenager although a couple are 5-8 (same age range as my child). They are Level One category.Obviously I am floored.
He explained to me that it was a boredom thing and he's not interested in little kids. His solicitor saw the actual websites and the images on there are all different ages. He reckons that the laptop has cached the images adn the police (plus SS) are just choosing the worse ones.
My partner is trying to get help. He is contacted the Lucy Faithfull organisation and he is going to attend one of their courses. He hasn't been charged with anything yet as the police investigation is still ongoing but seems to be drawing to a close.
The people are Lucy Faithfull are very helpful and they have said that most families come out of this on the other side.
I had a Child Protection Conference this week which both me and my partner were invited to. When we arrived, he got asked to leave, despite being invited!
In the conference, I was told that I wasn't putting the need of my child first, despite the fact that my child hasn't seen Daddy for 8 weeks, I'm actively keeping the school up to date, my childs education is above average. They see it as, because I want to get back together with my parner, then I'm not putting my child first.
I'm aware it's not going to be easy, but I thought it's in the best interest of my child and me to work on this. They see it as my partner is trying to groom my child (and me). Plus that he's controlling me because we're still in the house that he owns and if anything happens he wants to help me out financially.
My child has been placed on the Child Protection Plan and I'm seeing them in 2 weeks time to discuss further.
They have suggested that I end the relationship and move out of a house that we've called our own for 5 years. I don't think it's in my child's best interest to move home.
I do understand the severity of the images, but I think it's too soon to be making judgements without my partner being assessed and without the investigation being over.
Please help.
