Should I move in?

My bf and I have been together for 3 yrs now! About a year into our relationship I moved to a different city while we were broken up... We've been doing long distance for 2 years now.. And he asked me to move back an in with him... I can continue on with school and find a job there, I feel like we're at that step in life...I just don't know if it's the right decision to pick up everything and leave! & im also having bad anxiety over what my family will say.... Any advice?
