True. He did accept her this way before marriage. But I don’t see his requests as suppressing or crazy as OP is making it out to be.
I think the OP comes across as somewhat selfish…and if she truly is that selfish, she’d have made a better choice for herself in a life partner.
He is not right but I guess I fail to see how that releases her from her responsibility to make good choices…to take shaadi seriously…to honor commitments…to realize that marriage is not a mere friendship…etc.
Life before marriage and after marriage is DRAMATICALLY different…no matter how many guarantees you ask for…there are none aside from the pact you make with Allah swt to make it work.
