So sorry to hear what ur going through. Praying for u and ur family.
As much as you love your husband, your kids definitely need to come first. I agree that you should get out of a potentially bad situation if he isn't willing to get help.
If you want to talk, inbox me. I may be able to help.
I totally agree with 2ndTimeAround09212014! I wish you the best of luck!
I don't know if your husband gets violent when he drinks but you did mention that he has been arrested before due to his drinking - it doesn't sound like a good/stable environment for you to be in. You need to consider what's best for you and the kids... I think the shelter will be the safest place plus like you said they can help you get into your own place. Best of luck
