Trying to marry an orthodox jew as someone who is not

Looking for advice here: I’ve been dating a woman from an orthodox Jewish household for awhile now, and it’s recently gotten serious. She isn’t necessarily a practicing jew, but she was raised in an orthodox household and her family is very strict to the rules. What the problem boils down to is that she wants her family to attend the wedding, but they most likely wouldn’t because the marriage wouldn’t be legal under Jewish law. This is a dealbraker for her, and I was wondering if theres anything I can do. I was raised a Christian, but I’m not very tied to that faith.
