Anyone get legally married before their wedding?

I just got an email that my monthly health insurance cost is going up significantly. I’m getting married in October 2025 but now I’m debating getting legally wed earlier so I can get on my partner’s insurance plan and save a ridiculous about of money. I’m F32, marrying M31 in Illinois.

Has anyone done this? I’m mostly worried about feelings. Like if I can mentally be okay signing the paperwork months in advance. And probably not including our parents in the signing of the paperwork. My hang up is that doing this feels like I’m keeping a secret and lying to my family. But telling them feels like they’ll all inflate it and want to essentially plan a micro wedding last minute which feels overwhelming. But also not sure I want to pay $650 a month just to be more traditional.

Anyone done this? Was it okay? Do you still consider your wedding day your anniversary? Would love some guidance. TIA.

EDIT: We did it! We signed our papers. Everyone has been cool about it and we feel no different. And I’m now saving so much money on insurance :)
