Lostparent,
I could have written this post about 1 1/2 years ago. It is hard thing to do, but you have to do what is best for you and your daughter will do what is best for her. I filed charges against my son and his exgf. It was the hardest thing I ever did. I am glad I did it, but also miss my son since now I don't see him. I feel it is his loss not mine. You can force your daughter into rehab, but you can not force her to stay clean. She has to want it!!!!!
I know you will make the right choice for you, turn it over to your HP, he will guide you on this.
I will keep you and your family in my prayers
