Entering rehab was suggested to him because of the charges when he broke into my house. I also had a restraining order on him at the time.
So he's only done it as an alternative to prison. That's not someone choosing to get clean. I've known people in that situation, they try to get drugs when they're let out alone towards the end, they drink endless energy drinks and strong coffees trying to give themselves a buzz. They're doing nothing more than biding their time until they get out and have no intention of quitting.
He says we are the adults so we get to make the choices.
And the choices you make should be in the best interests of the children. Having him there isn't. I'm glad for their sake you've filed for divorce.
He keeps telling me I should give him a chance and the kids should give him a chance.
He can say and think whatever he likes, doesn't make it true. You owe him nothing. The kids definitely owe him nothing.
He puts things in my head and he's so good at making me believe him.
Which is a very good reason to run far far away and never speak to him, or hear him out, ever again.
He keeps telling me I need to give him a chance because he's never been to rehab before and he is clean and things will be different. What do I say to that??
You say you disagree. Your views on your and your DC lives are more valid than his views on your and your DC lives. He gets to make choices about his own life. Other people get to make choices about theirs. You get to make choices about yours. You don't owe him an explanation for your views or choices, he doesn't have to understand your views or choices, he doesn't have to like those views or choices and he doesn't have to agree with them either. He can 100% believe you are wrong, he can think it's unfair, he can be angry about it or confused or upset, and you can still make those choices. You don't need his agreement or his understanding and you don't need to explain.
