I don't know what to do anymore

On Saturday my oldest daughter came to take out family dog for a walk. I told her where I was leaving the key. When I got home that night I noticed that she didn't bring him home so I called her she said that she dropped him off at a dog sactuary in Quebec. I was devastated. My other daughter (17)was upset as well. The next day my 17yr old went to her sisters apartment to ask for the address where the dog was dropped and my 19 yr old called the cops on her saying she refused to leave. The very next day being Monday my 17 yr old came home at 11:30 and asked if she could go and sleep at a friend's house so they could go join a club in the morning. I said No because it was a school night. Then sometime from the time I went to bed til 6:30 she had snuck out of the house and drove over the grass to leave. I went to the school for 7am and there was no club, I then went to the friends house where she had asked to go and she wasn't there either. The girl and her parents had no idea what I was talking about. I went to the next place my gut was telling me to go and wow I found my car. I kept calling my daughter and the girl that was living with me and no answer. So I called a tow truck to tow it back to my house. That was the first privilege she was going to experience. Then I waited... from 7:30 til 10 am when she finally got to my truck. I was sooooo mad. I called her father and told him what she did and took her to the school and spoke to the V.p got her on attendance check-in and changed the password on the Wi-Fi. Later that same night she came tow and said she wanted to go back to live with her dad. I couldn't force her to stay but I did ask if she had anything to say to her step father and I.. she said No.I am so heart broken with everything that has happened over the last 6 days. I keep being told by my spouse that I did wrong but really how is all of this my fault? What should I have done differently? Maybe if I had have just slept in I would never had noticed and maybe she would still be here... or maybe not. Who knows. via /r/Parenting http://ift.tt/2xlCZOq
