"...to say she wants to move on from this chapter made it seem like she just didn’t want it to exist anymore. "

Bingo.

I am so sick of this phrase, from anyone. Being told that someone is moving on usually means "I don't want to talk about it or deal with it any more." and when people tell you you should move on it's an attempt to stop you from addressing something that's meaningful to you.

It's gaslighting.
