I have said for the last year and a half that difficult child can never come live in our home again, but once in awhile I start thinking, what if he's doing really well someday, would I change my mind?? Then I read a post like this and it reminds me of my answer, NO!!!!Not now, not ever!!!!
I agree that these are definite signs that he is still using. He is showing all the familiar signs.
You have to get him out of your home, especially now that you see how it is effecting baby girl. Never mind it depending on whether he's working or not, because having a job is not changing his attitude and the way he disrespects you.
He is causing your life to fall apart. Take back your life and make him take responsibility for his.
