I need advice

I'm recently turned 18 my bf is 19 and we have been togather for a year now and out of high school but I wanna start college and I don't wanna really work yet I wanna focus on college and he has a job and we want us to move in togather and he said he doesn't mind paying while I finishing school is it too early to move in and should I allow him while I'm in school to pay the bill by himself....he will not be helping paying for school I'm taking care of that and hopefully get a job on campus or something
