Well, any feelings more than friend feelings need to be gone, otherwise it can be awkward or start drama, so if this is happening then yeahhhh...what I said. And if he's just being retarded, then...he's just being retarded.
Be like "yo nigga, I just wanna be friends like before, if you ain't cool wit that then fuk you cause Idgaf bitch. and pretend like you don't care and leave...if he does want to be your friend he'll be like "oh shittttt" and come around.
