If my coworker liked my photo.. does that means he likes me?

Well he is ex coworker now and I had no big interaction with him. Many times I caught him starring. He is not my friend on social media or following me either. 5 am in the morning I received a notification from him liking one of my public photos. Out of the blue. It s weird because this happend exactly two days after I quitted my job.šŸ˜… Who does that?
