My Children’s father has been struggling with cocaine addiction for some time (iv known about 4 years). He says be wants to be sober but to me he’s not making enough changes in his life for this to be true. He tried NA but after two weeks said it wasn’t for him. He’s a very private person who doesn’t like talking about his feelings. We have three children together (ages 12,8 and 1). He owns the flat we live in and iv said multiple times that if he can’t sort himself out then I will have choice but to take the kids and leave and go back to my parents (who live 40 minutes away). This past week he seemed really determined to get clean, we had a week where I could see he was really trying. Then last night he must have used, he tried denying it but by now I know the signs and he’s gone back to bed this morning. He’s also lost his job recently because of his addiction and I was hoping that would wake him up but it appears it’s not. Do I give him a final chance to sort himself out or do I just call it a day now. I’m just aware that leaving means making my children leave their home and change schools. I also do want to support him but I just feel like he’s not doing enough to really change. He doesn’t seem to be able to stay off it more than a week. He’s also threatening that he will want 50/50 when he’s clean and if I don’t agree he will try full custody in court but at this point I feel like he’s never going to be clean! I just think he thinks as the flat is his that he has a little bit of power there and could argue the children don’t have to leave their home and schools.
