Does he like me (I like him)?

This guy who is a friend's friend, we only talk online because he lives in another country and we have met in person only once. We have a lot of common hobbies. I texted him recently (after a two months of not talking) to congratulate on his recent achievement (I got to know about it from a friend), and he replied with "Thank you, means a lot". And on the same day changed his display picture (Whatsapp) to a quote related to our common hobby that we bond over.
