It's nice you keep in touch with his dad. Nothing wrong with doing that. No this isn't wrong place. We are all from different cultural and ethnically backgrounds. No right or wrong. I don't believe your friend has ill feelings for you. He is just busy with his life. People often lose childhood friends over time. I doesn't mean he forgot you. Just that he moved on

I am glad you started to move on too. It will get easier with time
