What is my butterwort doing?

[KristenReuel]

Hi!

My butterwort had drastically changed shape/size since I got it in the summertime. I thought it might be in a dormant stage at first, but it does not match the pictures of butterwort dormancy I've seen. It's not really clear in the pictures, but it's also kind of split itself up in the pot too, so it's "sprouting" from three different points.

It produced 4 blooms in the summertime, and the leaves seem to be healthy and going nuts, but I have no idea if it's supposed to be doing that. I thought butterwort leaves were supposed to lay flat. Any ideas?

The first two pictures are from the summer, the second two are now.
