Is it wrong to move in with your boyfriend before your married?

I grew up strictly Christian and have been with my bf for 3 years now, we are in a tight spot in our life and may be thinking of moving in together to figure everything out (we can’t afford to live on our own/moving out of state so no friends for roomates)

We also have been very diligent on waiting till marriage so I have no issue with Sex being something considered in this. We just may need to live together before we’re married.

(Also, I’m 21, he’s 22.)
