Did I hurt this guy?

there's a shy guy who likes me I hurt him very recently via a letter afterwards he tried to call me two times in that week (I didn't pick up) then I told our mutual friend last week that he can call me since Monday no call from him. did I mess up?

is there still a chance of him calling me or is it over?

and another update: I didn't intend on hurting him it's just once we had stress and then he hurt me that day and after 10 min acted like he never said anything. in the letter I wrote for him i talked about how much that hurt what he told me that day and that i wanted nothing but to make him happy and that we better separate. i was just hurting so much inside yes I know I didn't handle it the right way
