Good luck to you in taking this very big step. I'm also in a similar situation, but thank God without small children. Take your time and don't let anyone pressure you or make you feel bad whatever you decide. Only you know what is best for you and your son. Take care of yourself in the meantime because all this is very draining and tiring.
Lilamy, thanks for this:
One counselor I went to years ago said leaving an addict is sort of like deciding to amputate a limb: You know it's gonna hurt like hell, you know you're going to have to learn how to walk (or write, or whatever) from scratch again -- but you also know that it's losing the limb or losing your life.
I love this and have to remember this one....so true....so true.
