Susan, I know you are feeling a lot of hatred toward her right now. I have noticed with my daughter when she relapes she seems to get right back on track. I know you are frustrated, but they say relapse is a part of recovery. I do believe you should stick to the boundries that you are comfortable with, but don't make anything worse for yourself. Give her a chance to confess and see where it takes you. I'm not telling you to be a whimp about it. I know if it were me, I would be steaming mad. There are no excuses for what she has done, I understand that, but see where this is going before you do something you might regret.
Prayers are coming your way. Hang in there, I am here for you.
Luv.........Lois
