Hey, so I'm trying to find this old fic where spike and Buffy first meet when they are going to different weddings, Buffy is with dawn.
Spike is a florist, maybe with Anya I can't remember but he does work with someone and a specific flower he talks about at one point is baby's breath.

Oh this one is one of my favorites! It's Blank Check by Cryptwarmer

Summary: The only thing certain in life is change. Will Pratt is trying to play nice with Dru, post-divorce, for the sake of the kids...as well as in the hopes of reconciling. Buffy Summers just wants to get her sister married without losing her sanity. Two weddings, one bar, a series of chance meetings and our favorite couple find themselves in a romantic tug of war, pushing and pulling each other towards their «new normal». 

Thank you so much, I haven't read it in so long and I suddenly remembered it last night ❤️
