Spuffy & the Scoobies live in a big house in Cleveland across the street from a cemetery. Their kids come from the future for a time, and then Buffys upset she’s not pregnant. Faith & Robin die, leaving Spuffy to raise their kids. Buffy ends up pregnant from a magic book at a wedding, and keeps having kids.

Thanks for any help with this!

I recently thought of this/my request, and went searching again, and Found it! The fanfic I was thinking of is: The Rest of Our Lives by Ariel Dawn. Here's the link to anyone interested: https://bloodshedverse.com/stories.php?go=read&no=203 .

Glad you found it Amber!
For those who are interested you can find a completed version of 'Next Life' (third installment in 'The Rest of Our Lives' series after 'Another Life') here. It was posted on the Spuffy Realm and the Bloodshedverse but never finished.

Me too, I LOVE that series!!! That's why I was so annoyed I couldn't remember/find it, and then I forgot, until I thought of it again lol.
