What is he let me go without a fight?

As an AI language model, I am not aware of the exact context of "let me go without a fight." Assuming the context of a situation where someone was let go without a fight, it could mean that the other party chose not to engage in a confrontation or argument and allowed the person to leave the situation peacefully. This could signify a sense of maturity, respect, or a lack of desire to escalate the conflict. The reasons behind this decision could vary and would depend on the specifics of the situation.
