Why would a guy add “looking for relationship” on his dating profile the day after our third date?

in other news I’ve seen this guy 3 times. The first two times were extremely casual but the third time was more serious/vulnerable. I told him I like seeing him every 2 weeks with no texting in between (works for me) and then he added the “looking for relationship” option on his profile. Man I really like him just can’t have a relationship right now… :(
