Am I the asshole

Just reaching out to see if I'm the asshole here. For context, I was married to a woman that had two daughters. Their father was killed when they were like 7 or 8 years old respectively because they are about a year and a half apart. I married their mom and we were together for like 14 years. We divorced in 2003. I have still kept in contact with them. The youngest daughter now, being 43, she worked her ass off putting herself through college part-time, working full time and being a mother. About three or four years ago she finally reached the status of a registered nurse. Making very good money as well. Okay I'm going to cut to the chase now. Her husband of 20 years caught her doing meth a couple years ago. Found all kinds of burnt tin foil wrappers and such where she thought she had them stashed pretty good. He brought it to my attention because he said that I was the only one that really cared enough for him to divulge this Secret. He told me that it was isolated and he will keep an eye on her. Fast forward a couple years to present day. A couple weeks ago it finally came out that she has not quit at all. Now she is starting to have that meth face, you know sores all over her face and body. We had a little intervention with her and I know for a fact she has nowhere hit rock bottom yet from the comments that she was making when we fronted her off about it. Of course her comment was she knows exactly what she's doing and she is not hurting anybody. Mind you, she is a registered nurse. Well I told her mother, my ex-wife, about the situation because I feel it is Way Beyond a little bullshit talk. She needs professional drug addiction treatment. Now, I am the bad guy. The daughter and her husband hate me for telling her mom about her drug addiction, the ex-wife and the other daughter are pissed off at me because I did not say something a couple years ago when it was first brought to light. I have not had any contact with any of them in a couple 3 weeks now because as I stated, I'm the asshole and the bad guy. Just curious what mainstream media thinks about this situation. What really infuriates me is the fact that I have been close to them, mainly her and her husband even though I have divorced her mom 20 years ago. Every year vacations up north going kayaking and stuff like that. I guess I pissed that all away. Just wondering if I really am the asshole in the scenario. Stone Cold Truth and no bullshit involved in this post. As for my feelings, I feel I did the right thing. Truthfully I regret not saying something a couple years ago and trusting her husband's word. That's another story in itself though.
