Bheema had faced with the Duryodhana in kurukshetra war..
Kurukshetra War happened in -6000.
Drathrashtra, he wanted to embrace Bheema, but a dummy of Bheema made of iron was shifted to him instead of real Bheema. Dratrashtra had strenth enough to crush the iron Bheema.

Because Kurukshetra was in between Hastinapur and Indraprasth and easily reachable from both ends.
God knows better if I am right or wrong but with my strong feelings,Radha being peace-loving person must have been deadly against war and she must had persuaded Krishna to avoid war and where he failed inspite of his best efforts and he felt ashmed to face Radha after Kurukshetra war that is why he did not meet Radha.This is KP Sharma om.sukhambhava@gmail.com
