It also will feel like your place, not hers, until you get some/a lot of stuff of hers in there or do some joint purchases. Beyond clothes and toiletries, things like pictures, dishes, furniture etc. Even layout and organization of where things are.

Just try and keep that in mind while you try to build a home with her, that you may need to get rid of or shake up your space/stuff a lot more than originally anticipated.
Edit: wow. Above posters in same mindset.
