I hooked up with this girl on saturday after our second date. This was our actual first "real" date. After we had sex she asked me "so, what are we." I told her that I don't want a relationship now. She agreed to that. On Sunday she says that we should be official again. Yesterday she showed up at my place unexpected to cook me dinner. After dinner she brought it up again. She texted me that we should go out on Wednesday. She also said she wants to be official. I keep telling her no but she doesn't want to listen. I'm thinking of telling her that she is turning me off with this relationship talk. I like her but she is moving way too fast for me. What would be the best way to do this?
