What does it mean when a guy says "maybe"?

Anonymous
This guy I've been dealing with for a while says "maybe" a lot I've noticed. The other nigh for example I've asked him "Haha so whenever you have a bad day at work do I make your day?" And he kind of paused, half smiled and said "maybe", and then he asked the same thing back to me and so I said "Maybe" as well. Another good time we had I asked him if I'm seeing him next week and he was like "maybe". He ended up calling the following week and made plans but it didn't work out. So I'm not sure why he says maybe a lot?
