I like a guy, I confess my feelings towards him, he told me he do like me but as a friend (rejected) but now he always pat me what does that mean?

The actual over all situation is, before confessing my feelings towards him I sometime felt he might like me because of the way he used to behave with me all ( spending more time with me then the actual group or other friends, being comfortable around me , hugging me whenever he is happy, patting on my head but after his rejection I got to know through my other friend ( the mutual one between us ) that he likes someone else and it was the reason he rejected me. I accept the situation. After the confession we were not that comfortable around each other but as time passed like after 6 to 7 months he started being same with me. Aahhhhhhh and he always pat my head ( daily ) please let me know what does this actually mean?
