I moved out of my rents place in the beginning of the year into a one bedroom apartment. It is close to work for me and really close for my GF. Basically she wants to stay here most nights then after so its not as far for here to drive. Saves her about an hour one way. The thing is I am finding I want my privacy sometimes. Every week night and then it turns into weekends too is a bit much. I have hinted to this but she doesnt get it. She says if you want me to go home just say, but I think she will take it the wrong way. How do I word it so that she goes home the odd time?
