1st question I want to ask that nobody else has is how long have you two been together ?
If it's only a couple months then ok slow down but if it's been six months or closer to a yr then just me I would say your trying to have your cake and eat it to .
Are you two and have you two been the only ones your seeing or is it still an open relationship where you both are together with poss of seeing others ?
After several months of being together it is only natural she would want to move in and become a 'couple' rather than just boyfriend and girlfriend dating ?
Does she want to move in to your house/apt or you move into hers ?
Either way that can become very tricky and a prob cuz first arguement comes up it will be 'this is MY place' and not yours . If you two are both renting apts if and when you are ready to move in together I suggest you get a new place together so it will be 'y'alls' place and not place of one or the other.
If you move in together will it still be equal shares for all bills or will you be expected to 'man' up and pay all ?
BUT if you move in together just think of all the extra money you will have left over for more guns and mods on your bike
