Is he dating anyone? Has he dated anyone since you dissed him three years ago? Well, he's right; many male/female friendship do have to die down a bit once a new SO comes on the scene. But his outburst says that yes, there are still some unresolved feelings. He might be over *you* but he may not be over the disappointment, humilation, perceived failure, etc. But another relationship should probably assuage those feelings in him...I hope.
