Hi there- Your lawyer will advise you about the children and, I agree, it's not a good situation for them...
You need to protect them and living in a house where cocaine is present and used is considered Child Endangerment. She could get in a lot of trouble if the authorities found out. Try talking with her to appeal to her good sense.
In the meantime, I wouldn't move out until the children were in a safe situation...
I've been through a divorce with young kids. I was 4 years clean at the time. I thanked God my thinking wasn't scattered and cloudy with drugs and alcohol at that time in my life. The one thing that should always be the most important thing for you to remember: put your own recovery first. Don't use no matter what. Everything will fall as it will, but if you don't use and learn to accept life on life's terms you'll get through this in the best shape possible. Get into aftercare. Get a sheet signed at the meeting. If need be, it will show all concerned how determined you are to protect your kids from the disfunction of drug addiction, and it will show you mean business with your sobriety. Stay clean for YOU and you alone, and your loved ones will always benefit.
Bless your heart. You may have a past, but you made the choice to get clean!!!!! Also, the different men coming in and out is not good! You have to do what's best for your children!
that's the best thing you can do, tell your attorney everything, not only about you but make sure he understands what is going on in the home and what it's like in a house filled with coke heads.
You've gotta get the kids outta there, especially if you have a daughter.
