Getting a verbal/written no follow up

It feels like too much time has passed to go back to this particular person and ask her why she didn’t sign up with me. I suppose if someone did the same to me, I’d think it was kind of weird, but I’d oblige them.

Now that I think back to that call, she said she needed to make sure she could financially handle it. We scheduled a follow-up, but then she canceled the follow-up through FB Messenger saying “Down the road I may reconsider but at this time I’m not sure we are the right fit.” She’s in my Facebook Group, but doesn’t engage.

I think my reason for wanting to go back and ask her is to get as much data as I can, but it’s like “liking” a picture on someone’s Facebook profile from 7 years ago. A little stalky with that much time gone by.
