What should I do?

I work in education. I’ve live in the same city I was born in and I attended college and grad school here as well. I want to move so that I can expand my horizon and maybe dabble in some other fields, but I don’t want to leave my parents or my boyfriend. I’m the baby of my siblings and no one will be here to help my parents if I leave. Neither one is sick or old but we’re very close. My boyfriend is the love of my life and we will probably get married one day. When I talk about moving, he always says that he will take me wherever I want to go just as soon as he can (when we get married). I’m thinking that if we make it, we’ll be married within the next 2–3 years. I don’t want to regret leaving or staying. What should I do?
