Do you think I'm a bad person if I've fallen in love with a 12 years old?
What are you talking about? You're 35 years old, how can you be in love with a 12 year old child?
She's an old soul. We've spent a lot of time together and she's very mature.
She's not an 'old soul', she's 12 years old. Not only is this extremely inappropriate, it's also very illegal.
I know she's young but I think we're supposed to be together.
She's a child. She doesn't know any better, but you do. It is not right to pursue this relationship.
