Marriage and insurance?

Hello all!

I’m very confused about what goes on with my health insurance once I get married and was wondering if anyone who has gotten married recently around my age has the answers I’m looking for

I’m 21 and me and my fiancé just got engaged (yay!) but one of the big things I’ve been thinking about is whether or not I’ll be able to remain on my moms health insurance policy, once I get married, as it’s extremely expensive here in NJ.

I’ve had people i know personally tell me that I’d be booted off, but I’ve done a good amount of research that says otherwise due to the affordable care act, any experience and advice would be welcome!

We won’t be getting married for at least a year or two, covid considered, so I have some time to worry about it but figured I’d ask.
