Boyfriends new job

I’ve been dating my boyfriend for almost two years, he asked me to move in with him 9 months into our relationship and I agreed. It’s been fun, getting to know each other and we’ve had our ups and down like everyone else. Lately he’s been unhappy with his job and his been searching for any outside our city. Today he gets a call for a really good job he’s extremely interested in for a long time. It’s three hours away from where we live now. He’s asked if I would go with him. And see I’m back in school, trying to make a better future for myself and I honestly don’t feel like it’s the time for me to move. I need advice. I’m not sure what to do.
