Thanks folks. So I've got long update and I'd apprecciate someones advice before I speak to WA further..
Woman from WA told me to call the police if he comes to property. He hasn't done that but he was trying to play on my pity for him to let him stay over, which I didn't.
Instead of changing the lock I will ask neighbours to change password for front door(there's that intercom-thing), hopefully they'll know how to?
If I change the lock I'll have to speak to landlord and my partner's boss is renting it to us since he took lease from that landlord so it's complicated. I lock the door when I'm at home so he can't use key, close the windows at night and when I'm out.
He also said he'll look for another place for me and our child because he can't afford this apartment since he has to pay for his room/place as well.
Problem: he said if I want to"continue cooperating"with him for visa based on our relationship/family I should make it appear like we're together in front of everyone, including WA in case their notes reach someone.
He wouldn't live here and we wouldn't be in relationship anymore but on paper.
The reason I'm having second thoughts is because I have better job opportunities here and my family is also abusive, I left home for multiple reasons and I don't want my child to come in contact with A LOT of people in that small town. In general my home country is quite of a hell for raising pro-feminist child(or to simply live there).
In other words, he never helped me get a job here so after certain period of time I'm here pretty much illegally until I can get normal job in Summer(when restricitons are off). He made it appear I'm self-employed on papers and arranged things but I haven't got NIN yet.
I think I will ask WA to let me take a look at notes they took so far(I think you can ask they said?), just so I don't get paranoid further...
Another thing is that I don't want social workers involved again-it's not neccessary, at least not what they could do. I'm taking care of my child the best I can and he's not lacking developementally or in any other way(they have confirmed that last time as well).
I feel that my legal status at some point will come in question in case I would proceed with acceppting their help. I'm just not that savvy to pull it off and I hate lying.
All I have asked from my"partner"is that he finds good abuser programme where they are in contact with me regularly to hear both sides of story and for his treatment to be effective.
He refused, saying he found something which offers group, 1on1, clinical therapy and so on. And obviously delicate flower as he is he will go only for someone who'll never question him, that is, 1on1 therapy option.
He is denying pretty much almost everything he did, calling me as abusive as he is, putting most blame on me and acting as if I am the one who should be grateful to him for talking to me.
I cannot stand him and I'm torn between risking my childs existention by possibly having to go back to my home country or putting up with his abuse from distance while hanging in the air.
How confidential is WA if they involve child protection and social worker services? I don't have anyone to just tell it like it is...
