bc where I live it is way too expensive to do so and with the career I chose (being a teacher) I would have to room with someone and I would rather room with my bf who I have known for 5 years and been with for 4 than room with someone I don't know.

Living in a flatshare with others is a great way to safe money, and become more independent, and figure out what you really want. You are young, and there's no rush to jump into living with your SO.... dating as financially independent adults will change your relationship, and often it helps to not take too many steps at once.

who I have known for 5 years and been

While you might have known your bf for 5....you have no idea how living together will be, especially if his family is involved too. I'd give the situation more time, get a job, become more independent first, and see how the situation looks like in a year or so.
