This is a nonsensical response ignoring the intrinsic relationship between morality and the information given.
Since the situation is intrinsically related to morality. My advice is therefore also related to morality. Just because the OP doesn't specifically ask for a moral answer doesn't preclude me addressing morality.
Betrayal and ownership are subjective in this context. However, there is still a majority consensus that can be arrived at based on the information given. Many will come to a single conclusion on who is the betrayer and who morally deserves ownership. When a person thoughtlessly steals his best friends girlfriend, what do you think the majority consensus will be?
