Are you saying that he's no longer talking to you but hasn't officially broken up with you?

Yes, that's exactly what I meant

If he isn't talking to you,what can you do?

I would,after some time,assume,that he's too much of a coward to break up in person and I would go back to living my own life without him in it.

If he cannot be straight up and honest, then you must be, and let the fool go.
