I also set boundries that I can stick to. That way she knows that I mean it and I don't go back on my word. I think boundries are different for everyone. You can only do what you are comfortable with. No one can tell us what boundries to set.
We all have a different tolerance to what we can put up with. For me I would not be able to put up with any drug use in my home. I'm not saying it never happened.....because it has, I just didn't know it at the time. That is definetly one thing that I will not tolerate ever. Do what is right for you.....nothing more and nothing less.
