If you're over 18 you have every right to live on your own. If you're under 18, and can prove you can support yourself without going on Welfare, you can try to Petition the Court for Emancipation. Of course, telling the Judge my Mom nags me to clean my room and go to school, is not going to get you Emancipated. So you need money for Rent,plus 2 months Security, Utilities (gas & electric), reliable transportation to and from work ( car, with Registration & Insurance, gas and maintenance). Oh yeah, food, you have to eat. You might want to add all that up before you even consider trying to Survive on your own.
It all depends on the sitution. Like if you are 18 and think that you are ready to live a life on your own then yes but just remember that your mom only does so cause she loves you and cares about you.
We cannot understand the care & love of parents...till the time we become parents... & start raising our kids.... It's quite sensitive... Parents are responsible for us....they want us to learn..what is good & bad for us... you are lucky enough..you have mom... enjoy this status.... try to learn...how to fix this problem... like you stay with mom...but she should give you proper liberty to enjoy your life ... discuss with her...tell her how much you love her...& you know ... she cares about you... but at the same time ...you want to sail your own boat... :)
