There have been other threads here where women have lamented the inability of men to distinguish what women deem to be acts of friendship for something more. I expect your friend is hurting quite badly now. As long as he retains any hope of a romantic relationship there will be a problem. I would not be surprised if he pops in now and again until it fully sinks in what he wants is not going to happen. Thereafter, I also would not be surprised if all contact stops.
