STBXH moved out almost 3 weeks ago. We rent a house jointly and he is still on the lease so legally he has a right to enter the house.
However, he assaulted me the night he moved out and I called the police. We have a DS aged 9 who was not here at the time of the assault but he witnessed the fallout and the presence of the police. STBXH was not arrested and charges were not brought because I asked them not to do so.
H still has a key to the house though he no longer lives here. I had initially said that he can see DS whenever he wants to. However, I don't think that this is tenable after all. He knew DS had a friend over this afternoon but still came over to see how DS was. He asked me if there was any chance I had changed my mind about the marriage and when I said no, he said that he would then be going for custody of DS. I asked him to leave and he refused (this was all done quietly so that DS and his friend could not hear).
I said if he did not leave I would call the police. H said he was not being serious and he would not go for custody and that the situation was very unfair etc etc. He eventually went to DS and said he had to go because mummy said he had to!
He then asked me if he could still see DS whenever he wanted to. I said of course he could, but he should contact me first in case we were out or to make sure that we would be home for him etc. He got irritated and stormed off.
So, eventually my question: how can I set boundaries? How do I make sure that he does not just pitch up? If he does and I turn him away then DS would get upset.
H originally agreed to be released from the terms of the lease but has since said he will not. Landlord had agreed to release H and then rent the house to me.
What the fuck do I do?? I dont' want him coming here and messing with me. I was fine today until now - and he has fucking upset me all over again.
