Moving in together is a bad idea. Sorry for being blunt but if shes not sure she wants to stay with you, I'm pretty sure thats what she means. Idk how old you guys are but moving in together after 2 months of dating (and not even really dating the last 2 weeks) is imo the last thing you should be considering. From what you've said, shes trying to dump you the cowardly way. You deserve someone that will always treat you the way she treated you in the beginning. Keep us posted! Be strong. Don't let her hurt you any longer.
