sorry that you are going through all of this, your life can get better but the choice is your. you can change him and his actions but its up to you how you allow him and his actions to effect you and your kids. maybe its time to focus on the life you want for you and work toward that goal. do what you have to do the make your life better with or without him. maybe start by setting boundaries that you can stick to. i agree with the others, him using drugs in the home is putting you and the kids in danger. keeping you and yours in my prayers.
