It's likely that the speaker is using the verb see in the sense of 'take in information with the eyes'. That is, she is probably talking largely about the behaviour of person A that she has observed visually.

The grammatical pattern used can be expressed like this:

have trouble doing something

 

[Tdol]

The person hasn't noticed any improvement or difference.

Seeing is a verb in the sentence.

Al: Loving her has made me a better man.

That's another way of saying the same thing.
