<human>: Can you give me the gist of the text in a nutshell?

A girl I've been seeing for a few weeks went to rehab for reckless driving and admitting to using crack, coke, and smoking heroine in her past. While she was there; she told me she passed notes with a 21 year old (6 years younger than her) guy who was there for 3 months for heroine. 

5 days after she's out, they're friends on Facebook and she takes a two hour trip down state to see him on my day off. She claims they're just friends and she can relate to him since they both hated the halfway house they stayed at. They walked around downtown, watched TV, and cooked food all day. 

Upon asking her if she likes him she said no, but said he likes her, and she failed to mention that I'm in the picture. I'm already jealous and suspicious since she never once drove to my house (10 minutes away) and turned me down for sex **the same night**. "I'm just not in the mood, plus my parents are home". She says I can see the notes and their IM transcripts because there's nothing in there she wouldn't want me to see, but I didn't check. "Can't I have new friends, ones that are guys?" 

Usually this girl never has a problem with fooling around but did tell me she wanted to remain exclusive and abstain from sleeping with other people. So I'm wondering if she actually wants to be friends with this kid so they can relate, if she's fooling around with him, or if she's looking to meet people for drugs. (Despite saying she won't do them anymore...pffft)
<bot>: girl visits guy she passed notes with in rehab 2 hours away, says he's just a friend; not sure if she's doing drugs or him.
