<human>: Summarize the given text in a few sentences.

So... here's the deal. My best friend started smoking a lot of pot last summer. She moved out of the house right after she graduated. She partied a lot, smoked, etc. Most things that young adults do once they get out of the house. (I did the exact same thing, but I've settled down and I'm married now) 

Things eventually got worse with time. She got caught with weed twice. And her dad being a independent baptist pretty much disowned her. Well, in late April (I had lost contact, told her I didn't want to speak to her till she stopped the drugs. Because, it got bad) she got into selling her body for money, and cocaine, and weed. Her father somehow ended up with her phone and found out and decided it was time to intervene. 

She called me the day before she left, saying she was sorry, that she loved me, and that she wish I could come see her before she left (I was 4 hrs away at the time) She said her father was paying for her rehab and that it was at some all girls ranch somewhere in KS/OK. 

Well, that was in May. It's October now. It's been 5, almost 6 months. And I haven't heard a word. She knows my number by heart and I visited her parents to give her a letter. No response. 

Something just doesn't seem right, and isn't right that her father isn't letting anyone contact her. I can understand rehab for cocaine but she only did it a couple weeks. And marijuana? Give me a break. I quit cold turkey and I'm doing fine. Apparently she has to stay there a year. 

I just want to know if you guys think her father is being to extreme? I'm going to go talk to him tomorrow to try and get some answers and give him another letter for her.
