Courtney, I'm so sorry to hear about your friend, and the troubles she is facing.
You've received some good information / advice here, and the only thing I would caution is that if YOU call and report him to the RCMP, SHE might also get caught in the "net" if there are drugs found in a "common" area of the house (i.e. kitchen, living room, the master bedroom they share). As a former LEO in Ottawa, ON I can guarantee you that she will be implicated as well if drugs are found in a common area, if reported by an anonymous phone call. She will then get charged / maybe convicted, and then she'll never get to have a license to do her daycare again.
As for helping her, honestly, there is only so much you can do. A very very long time ago, I was your friend (minus the children, and minus my own business in my home). At the time I "loved" the "bad boy" that I was with ... the whole image was fascinating (I was 18 to put into some sort of context). It took me losing absolutely EVERYTHING before I woke up and came to my senses. The police were at our house at least monthly ... I never laid assault charges on him, b/c it would only have made the situation worse, and back then, the police didn't have the law they have now - charge him anyway if there's proof. I lived like that for 5.5 years. There is "SOMETHING" about him that your friend loves, and wants to see again, and is living for the hope that it will ressurect in him again.
Until she realizes that it's GONE and GONE for good ... and she's not losing more than she's willing to (women in these situations are amazing rationalizers ... I was one of the best) then she will stay with him.
It absolutely sucks to be her friend right now ... my best friend of over 30 years stayed on the "fringes" of my life when I was with my b/f at that time, and she said it was horrifying to watch me throw everything away for him. She just hoped and prayed that one day I would wake up and smell the coffee. Thankfully, I did, and I was still young enough to put my life back on track and move forward.
Hugs to you for being there for her, and I hope she comes to her senses soon.
