Moving with my boyfriend?

I am 16 years old and have been with my boyfriend for 2 years. We met the summer before my freshman year. He was a senior and I was a freshman. He took my virginity and I couldn't ask for anyone else in my life. Our relationship has had ups and downs but I think were starting to trust each other and really know we want to be together. He is 19 and wants to start his life by moving to Chicago il for a job opportunity with his family. I support him in wanting to get his life going but he told me he wants to wait for me. He wants me to finish high school and move with him. He said his aunt could get me a really good job there but ive lived in Texas my whole life and all of my family is here. I'm not sure how everything will work out. Any advice?
