You mean you don't let her spend the night? No morning-glory-story? No breakfast? Eish, Julius Malema calls that rape...
Uhm, no. Did no one ever tech you the rules of manliness? You never do anything at your place. Ever.
1. She now knows where you live.
2. Cleaning the mess you made the next morning is your problem.
3. You have to think of some stupid reason to get her out of the house the next morning.
4. You wake up and want to puke. Then you turn around and see her sleeping face.
5. She wants to take a shower and has no extra clothes, meaning you have to give her some of yours.
6. If you did things right, there's some serious damage all over the house. Broken tables and vases, the chandelier's in a million pieces on the floor, the railing next to the stairs is somehow missing and your pants are hanging on the tree outside your window.
Avoid this horrible situation by simply going over to her place. That means you can leave when you're done.
