Moving in after 1 Month… Too Soon?

My boyfriend and I have been together for a month, I know what you’re thinking already but listen Linda.

We are on the same page about everything (how we feel about each other, what we like and don’t like, what we want out of this relationship and our personalities are similar).

I’ve started a new job in his city and am moving from my old house a couple of hours away. He wants me to move in with him and his housemates, so do his housemates and I want that too.

My question is how soon is too soon and why? Has anyone has success with moving in with their partner so early?

Side note: Who made these rules about when you should do certain things in your relationship??
