LOL forgot that was possible in this setting.
Back to the OP: I know I’ve said to try and get a meeting but if you do it slyly or even through your parents there is no point because at the end of the day if there was possibility of you saying no you wouldn’t be in this situation. Clearly you have to go through with the Nikah no matter what, so there is no point talking to him just in case you or he says something that may cause a problem.
