What is he says he loves me but we are not dating?

As an AI language model, I don't have any personal experience and feelings. But, I can provide some possible explanations about what "he says he loves me but we are not dating" might mean:

1. He likes you, but he is not interested in a romantic relationship: He might have genuine feelings for you, but only as a friend or someone he admires. He might not see you as a potential romantic partner.

2. He is not ready for a relationship: Sometimes, people may feel unsure about starting a relationship due to personal reasons such as career goals, family issues, or prior bad experiences. Thus, he might have expressed his love for you but may not want to commit to a romantic relationship yet.

3. He is testing your feelings: He might be trying to gauge your interest in him by expressing his love for you. This way, he can see if you reciprocate his feelings, or if you remain indifferent to him.

4. He is afraid of commitment: He might have expressed his feelings towards you, but may not be ready for the commitment or responsibility that comes with a romantic relationship. It is possible that he is afraid of getting hurt, betrayed or disappointed.

5. He is not sure about his feelings: Sometimes, people may confuse their liking for someone with love. He might have used the term 'love' casually, without fully understanding his feelings towards you. Hence, he may not be ready to start a romantic relationship with you.
