It's abit long winded but any advice would be really helpful!
Me and my ex split up 3 years ago now ...we were together for 7 years not married and have two children together. Ex is a big drinker and can be aggressive and a big emotional abuser. When we split up he hardly saw the kids and sometimes when I went to drop them off of a weekend he stunk of alcohol so I never let them go obviously.
After we split up he tried to take me to court for access but ended up not following through, it was at the height of covid and all the conversations were on the phone which i followed through with until a judge completely dismissed the case. Since this he has had 2 other children and lives around 10 minutes away from us. He has never been to my children's school , picked them up after or taken them to school ... he has never given them food after school or had them over the half terms despite asking if he wanted to see them. After he got with his current girlfriend I was happier letting them see him as it seemed at the time she enjoyed taking care of them. Since they've had 2 other children though my kids don't get a look see ...he sees them twice a month on a Saturday 9am till 5pm and even that was bought back from 6pm because they said 'it was too late for their other kids' myself and my ex cannot communicate together..he is aggressive through texts and i can't handle the stress as I'm currently pregnant with my third child. I was having contact through his new partner but he has now resorted to arguing and being disgusting through messages through his girlfriend. I'll also mention that our youngest child together is a type 1 diabetic and her diabetes is not managed when they see her at all the kids have one meal with them and it's always a mcdonalds which is something she shouldn't be having often because of how it effects blood sugar.
After a recent slur of horrible language and refusal of communication I've cut contact and told his girlfriend to pass on that it now needs to go through the courts I no longer want to communicate with either of them and that if he wants to be a responsible parent he can't just have them for a few hours twice a month. I'll also add my children had been coming back stating that him and his girlfriend have be violent towards each other shouting and swearing and pushing and that it has made them both cry and also the other child at the time in the house cry.
Because of stopping contact he's also stopped csa... am I in the right to say we can longer communicate and that for the sake of the children it needs to be sorted within court because I can't handle the stress my children have multiple times expressed that they do not want to be there and that they are glad to be back my oldest daughter also told me she wants to decide when she's older whether she wants to see him or not..
Advice please anyone have any words of wisdom ??
