Where's ur pride?...Has he taken that from you also?...Children should NOT be in a home when the parents are "drugging"! If you love ur kids, you'd get out! But are you just thinking about urself?....You'll never know the answer until you make a clean break, and get on with ur life, give ur kids a good, clean life!
I've been there and done that! For 5 years! It's possible that leaving him and taking the kids, might wake him up! Then again, he might choose the drugs over you and the kids. That's something you need to find out!
You are risking losing ur children! The State could step in and take them away from you! I know, because it happened to someone that I know, and she lost her 2 kids for 8 months!
My advise is to get out! If ur husband loves you and the kids, he will find a way himself! You can only help someone, as long as they help themselves! And apparently, right now, he knows you're not gonna leave him! So, he's "walking all over you"! Even stealing from ur family!....That is very low! Not worth it!
