Ditto what the others are saying - until you are 18, your parent/legal guardian has almost all the say over where you go and what you do.
And, as one who deals with teens all the time and the father of three who are now over 18 and one that will be in a few years, I have to say that the two oldest who have moved out said the same things you did - that they had it handled. Ironically, both of them still rely on mom and dad for things like medical insurance, car insurance, new tires for the car, auto repairs, grocery infusions, co-signing for rental agreements, pay for cell phone plans, books for school (tuition is covered by scholarships and waivers for the most part), and they still have to try and work as many hours as they can. Stoneheart, it is not as easy as you might think it is. And unless sissy and boyfriend are independently wealthy, they are not going to be able to provide much help to you. And, if they do, and you become dependent upon that aid, then they will control you - be especially wary if it is the BF that tells you he'll take care of you and keeps you from getting your own place or supporting yourself ... if I had a dollar for everyone of those relationships that went south in a bad way, I'd be rich!
Now, be honest, the REAL reason you want to stick around is the boyfriend, right?
