He blushed when I kissed him on the cheek...what does it mean?Is there any chance he likes me?

there's this guy that I met him 3months ago..i had a huge crash on him...we're kinda talking and barely went out 4 times...i'm not sure if those can be counted as a date tho! yesterday afternoon we went for a walk to American river in auburn and had a great time...anyway at the end of the day he gave me a hug and I just kissed him on the cheek and hugged me again and he blushed...and he pretty much acted as usually...does he like me?
