How to protect my Children from their father

[Glittabug]

I have ended a long term relationship due to a series of incidents from my ex partner which I no longer accept continually crossing my boundaries. There was a lot of back and forth him begging saying he been to therapy he can see his errors then one final incident his mask slipped I it confirmed that the relationship was ending.

We have a 8 year old daughter and 3 year old son together. We still live together, the house is getting sold.

I have always maintained that I want to remain amicable with him in the best interest for the children however there has been a turn in my ex partners behavior.

My concern now is that he has been telling my daughter that I am seeing someone else (not true) he been reading her the Bible shouting and ranting about God, liars and betrayal, and he is going to have a prayer room in his house and she will need to pray every day. Also telling her that he is a clairvoyant and someone in the house is sick and is going to die, telling her that I'm going to face my consequences. When she asked what about his consequences he said her don't take sides! He is also shouting and singing loudly in the house.

My main concern is that has shared with me that she is scared of him she has never seen this side of him. She wants him to stop ranting about God and talking about me but she is scared to say anything, I can't talk to him there no point. I don't talk to him and I don't want to engage with him at all. I want this to be documented however she is scared that he will find out that she has disclosed this information.

I provide a safe space for her to talk I'm not sure that to say to her all I do is apologise and reassure her that once we are out of the house we won't have to deal with this.

My questions are:

1. How can i get what she is reporting formally documented?

2. I want to have formal child arrangements in place is mediation the first port of call?

3. I want to get her into therapy is privately the only route?

Look for local charities who can offer funded play therapy where you play a voluntary amount. A third party documenting it is best.
Mediation is a first step, unless abuse of any form is at play. I think it is very hard to sometimes see it could be abuse, so think carefully.
You also aren't wanting him to have the kids due to his extreme views, involving the kids with adult issues, badmouthing you which could lead to the breakdown of your relationship wjth the kids. So mediation may not be the best place for you.
Speak to school and nursery and keep them updated about your worries. The kids may disclose something and if the school don't know about the bigger picture they might not understand the severity of that discloser in the bigger puzzle.
See a solicitor- it is really important to get legal advice even if you don't need court or you self represent. Knowledge is power.
Follow LegallyNik on instagram, abd document everything that is happening. Evidence wherever possible.
Sorry you're going through this, it is so tough.
Lastly, please get a safery bag together and leave it at a family member's or friend's house. As the time comes where you no longer live together, his behaviour may, potentially, escalate. Have everytbing in there you need to leave. Pjs, school clothes, passports, copies of paperwork, everything.
Change all your passwords to something random.
I say this kindly, I am Catholic, so being religious does not worry me. But it sounds like religion may be overbearing in this situation, and every religion has some extremely strong views, so keep doing whst you are doing with your open dialogue so that misconceptions can be discussed.
Lastly, consider helping your kids develop critical thinking skills. The Sky is Red is a great book for this, loads more too.
