When is it okay to move in with him . .?

So this may sound super crazy ; I am 17 and i am a very determined / independent female - I have big dreams and plan on going to PACE or NYU in the city to pursue my goal of becoming a forensic technician ; I am ambitious but im also the 1st kid going off too college wl parents Pr / colombia ... they have no experience and no financial support to help me nor credit to get good loans otther than PLUS loan . I have some scholarships and am workingg on getting others, im only a junior. But my bf of 10 months who i see my self with for a long time has brought about an idea . hE WILL BE living on his own soon , with a job he got through college he has a 4.0 and full ride in college so he can save up but hes offered for me to live with him and not pay rent which i was shocked at and said i would want to pay rent and get a job cause i dont like feeling like nothing . . . but anyways should i think about this if we last thru my senior yr ? he already lives in the city ... WHY OR WHY NOT <3 AND YES i love him , but i dont want to write too much cause i know most will not read it haa ! --thank you .
