One thing that I have learned in my six years after high school, and after three boyfriends (two ex's and "it's complicated" one), is to never move in early if you don't feel right... give the relationship at least six months to a year before even considering! And none of this, "But baby, how are we gonna know each other if we don't live together?" kind of crap logic, lol.
Some men in relationships want to have their cake and eat it too. Some men really need to merit that cake first, and show me that they are mature, ready, and able to have a good and stable relationship!
