Worth it to wait?

So there's this guy I really like (I'm talking super big crush), and I asked him out- we went and I had a great time. I am extremely shy and I felt totally comfortable talking to him, which was crazy. There was of course some first date awkwardness, but it felt like we clicked. Afterwards I was effectively friend zoned (unfortunately I work with him so I have to see him doesn't make it easy)- he said he felt there was too much of an age difference (only 4 years, and I feel we are very close in maturity). This doesn't bother me, but I understand and respect his choice. However, I still feel there is some chemistry and so many people have told me that they think he likes me. My question is- does he like me but doesn't feel it would work now and maybe I have a chance later - or does he just not want to hurt my feelings and is definitely not interested?
