Answer:
The underlined portion of the sentence "I might have felt in refusing you, had you behaved in a more gentleman-like manner" is an example of a "conditional clause." Specifically, it's a "past unreal conditional" clause, indicating a hypothetical or unreal situation in the past. This type of conditional clause is often used to express regret or disappointment about something that didn't happen. In this case, the speaker is expressing that they might have felt differently if the other person had behaved differently in the past.
