Part one has had 207 readers with 5 comments, and part two has had 122 readers and 4 comments
I think if your part 2 has over half as many readers as part 1, your story is doing really well. Yes, definitely lots of readers hunt for the good parts and skip the rest. But that would happen if you crammed it all into one part, too, it's just that it wouldn't show in cruelly stark numbers.

Also, I object to the idea that 6500 words is a 'long' story. I know attention spans worldwide are on the decline due to social media and stuff, but geez.
Author: Would you like to read a story about your most secret, most arousing kink?
Reader: Yes.
Author: It's 6000 words long.
Reader: Oh, okay, no.
