My husband came back today even if he is still using and right now I am too tired to either leave or ask him to leave.
yeah jt's a big move that looks even bigger when you're considering it.
I agree with Back and Scared tho - as an outsider reading your posts you the kids and your husband all together in the same house doesn't seem tenable in the long term and may not be safe in the short term.
I hope you'll make a decision based on your and the kids best interests.
