She behaves as if I am the only one for her. But I don't think so from what I have seen. So why do I want to show her I know?! At first I thought she could be more than a fuck friend and we could make deep conversations and tell each other things not all know. Plus I don't want to look like the dumb one(though now I look since I am writing this)

Long story short I thought we were exclusives but now not anymore and want to show her, but not telling her straight forward. How can I do that?
