Well, Aragorn was never betrayed by a person who he thought was his ally . . . not personally anyway. Gollum totally betrayed Frodo's trust, Feanor turned his back on Galadriel and her kin on the way to retake the Silmarils, and Turin was betrayed by Mim the Petty Dwarf. Galadriel and her brother and kinfolk went after Feanor to avenge themselves . . . Turin paid back the Petty Dwarf, and Frodo had faced off with Gollum on Mt. Doom. Ill omens and doom had something to do with each betrayal (Mt. Doom, Doom of Mandos, Glaurung's Curse).
If the answer isn't somewhere in that jumble of linked pieces of information, I give up.
