Definitely #2.
Being an FA doesn't require her to be into this explicitly. It's also much easier to find someone who clearly doesn't mind being fat.
If anything, if she's the sort who's worried about not being skinny, it may even be a relief for her.
It also seems quite unlikely I'll meet someone who's into this, or will admit it, even to herself. But there's plenty of fat women out there, so they're far easier to find.
Also, for a relationship to work, a lot more things would have to shared. That I like to see weight gain is a pretty small part of who I am overall. She doesn't have to be into feederism in particular for it to work.
