Might be helpful to inject some more structure in the time you spend together. Like if she prefers schedules, you could get a calendar and mark days/times when you want to spend time doing certain activities, or maybe other days where you are together in your place but have time to do things alone together... if that makes sense.

My gf and I do this, where we set up an hour or two a day where we both go into our own rooms and spend time alone doing whatever we want. We are both kinda introverted so it helps us decompress and relax.
