I've NC for this because I think he knows my NN on here.
I kicked him out three months ago when he hurt our DS throwing something at me. He came over a few times to see them but after I said he couldn't stay the night (he would get aggressive etc if I tried to get him up in the morning, I had to work so couldn't leave him there... you get the picture) he refused to see them at all. That was about two months ago and he's not seen/spoke to them until yesterday.
Things have been getting better between us and he asked to come over, which I said was fine. I told him it would have to be outside the house but he refused, saying he wasn't being dictated to. Worked that out eventually and he asked about my life etc. I told him I'd seen a friend which he took exception to (because I 'fancy him' apparently), and refused to see them if a certain different friend was in my/their lives.
Now this friend has had a far from ideal past, he had his own DD removed a few years ago because he had a drug habit. He has since moved past this, and is clean and hard working. He's happy for me to do a police check, and I've seen all of the SS reports saying he is a good dad now, and that there's no plan or protection against him seeing his DD.
Ex is unstable. He lives with his Mother, who has had her own DC's removed because of a boyfriend ten years ago. He has tried to commit suicide 6/7 times since last month, and he is unable to look after the DC safely. This is documented, I made sure of that. We had a few instances of bad neglect when they were in his care so it's not me being awkward, he really isn't safe.
If he takes them, can I get them back? Will they take him seriously if he says I'm unfit? They're 2 and 3. I'm really worried, and his Mum is on the warpath too which means she can take him to get them from Pre-school.
