I'm really hoping this is a hypothetical question and you have removed the man you've spoken about on here for months from you and your children's lives? However based on the previous threads I'm sure this is about the same man and you're either still with him or in regular contact with him.
He is disgusting and abusive. You at this point (if you haven't cut all ties with him completely) are allowing a violent and abusive man to be around your kids. He was living with you all. You said they were sad. He was sexually assaulting you regularly. If you're still in contact with him then you need to go no contact.
If you're still in a relationship with him then I'm sorry but at this point you're being cruel to your children by choosing to have him in your life. You are also showing incredibly poor judgement and decision making. I understand you've been abused by him and that's awful. You have had times where you could cut him off. Your kids have no choice in this. I feel so so so bad for them, poor little things.
he used to be a coke head and his last relationship ended due to him picking females from his dealer to have sex with for a fee.
I'm so so so unhappy. Beyond unhappy. This man has ruined me
He was to go to prison 9 months ago for assault, criminal damage and coersion. I changed my statement. We got back together.
Do the right thing. End it. Move on. Get counselling to avoid bringing another abuser into your children's lives at all, let alone their home.
