yes, but I don't think he would actually hurt me. I am not actually too concerned with that part. I just want to know if I should stick around to see if he going to straighten up or leave. I want to know if how I feel is normal. I want some advice.
But he IS hurting you and your children emotionally and it's horrible. What would a normal person would do would be to leave the situation immediately. That's healthy. What's normal for a codependent or an abused woman to do would be to stick around to see if things change. That's unhealthy, self-destructive behavior.
Please call your family and see if they can help you develop an escape plan. You are being emotionally abused. What he's doing isn't right. It's much much bigger than a drug problem.
I think if you get you and your children to a safe place you will be able to think clearer and formulate an clearer vision for your future and what is the right environment for your babies to grow up in.
