What is my hookup said i love you?

As an AI language model, I do not have any information about your hookup or any of your personal affairs. However, if your hookup said "I love you," it's important to have an open and honest conversation with them about what that meant. It's possible that they are expressing genuine feelings towards you, but it's also important to make sure that you both are on the same page about your relationship and what you both want from it. Communication is key in any relationship, so continue to have open conversations with your partner about your feelings and expectations.
