What do I do about this???

I'm 21 my boyfriend is 19. We were living together but our roommates were CRAZY
So now we live with our parents
I was going to try to live with him and his dad but there really wasn't room for me and my things (which is fine)
My family is VERY negative so I'm really not here that often I stay at his house A LOT
So when I'm home I can't sleep...I'm just so used to being with him
I know I have separation anxiety 
But what am I supposed to do about this???
Side note - We can't afford an apartment at this time
Within the next year we should be moving to NC for his schooling
