Q:

What is the right word for this sentence?

"I'm just remembering how ... I am about this guy"

I don't know what to say. I need a word that describes either when you don't know what you think about a person or when what you think about the person changes.

A:

Perhaps uncertain will work for you.

Uncertain
adjective

(of a person) not completely confident or sure of something.
‘An uncertain future’

Not able to be relied on; not known or definite.
‘I was uncertain how to proceed’

(OED)
