I ruptured ligament, a torn ligament, and 2 bone contusions. I was never immobilized. 3 months ago in ankle. Still pain. Is surgery necessary?

Maybe. Need to be evaluated by specialist to determine damage that has occurred and what can be done to fix this.
Need full evaluation. With torn ligaments three months ago and ongoing pain, you should see a foot and ankle surgical specialist. You might need surgical repair of the ligaments to try to return to pain-free living and walking. With that said, torn ligaments that don't require surgical repair can take many months to heal to a sufficient degree to allow a pain-free state.
