Can I legally be on my own in louisiana at 17?

I am 17 and I live with my 22 year old boyfriend. We have been living together since I was 15. We are waiting until graduation to get married. I have been taking care of myself almost all of my life and now I'm on my own. Is it legal in Louisiana to be...

17 living with a 22 year old if you are proven responsible? I want to start getting my life started and I don't know if I have to wait until I'm 18 or am I safe to start now?
