I read this whole thread, and you sound a lot like me when I was 15. Though, that was such a short time ago. (only three years)
I was in a controlling relationship and I hated it. Lucky for me we moved away so I couldn't date him anymore. It was bad at the end though. He started hitting me. He was 18 I was 15. It was horrible.
I understand what it's like to live in a scary town. I live near Dallas, Tx.... it's pretty scary here.
