One simple fact I hve learned is how pathetically inadequate verbal comunication is.
A famous philospher once said -
"By the time I have finished this sentence, you will have started to misunderstand what I am trying to say ..."
and that's about the size of it.
Your friend may have heard some erroneous input from parties unknown, so the best thing is to talk it over with him.
Yes, talking is often less than useless, but we have to minimise the problems by keeping pure communcation channels open as often and as long as we can, so have a chat with him.
Worst case, he continues blanking you - you move on.
Best, misunderstandings cleared up, frienship moves on, stronger - result!
Call him ....
