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

Hey Reddit! Not as serious as some issues on here, but I would still love some advice.

I've (F20) been dating my boyfriend (M 20) since April 2012. He wants to take me camping during the summer after I finish my spring class. Although I'm not really outdoorsy, I'm willing to give it a shot. Unfortunately, I don't think my mom's going to let me.

I live at home while attending college. My parents have agreed to pay for my college if I live at home. So I'd rather be free of student loans than have the "college experience".  

I've asked my mom once before about going on an overnight trip with my boyfriend. She pretty much said no with no reason to back it up. She's kind of old school. I feel like I'm more than trustworthy. 
*I do great in school. I even have a great transfer scholarship for next year.
*Not really a party animal
*Always home at a reasonable hour because I know my parents work early.
* I handle responsibilities well between work, school, private tutoring, and babysitting.

Yet with all of this, I still get a no. Part of me wants to screw her opinion because I am an adult, but the other part of me does not want to mess with my free college and housing. It's not like my boyfriend is a stranger. He's usually at my house once a week and she seems to like him. How do I approach my mom to let me go?
