Great Expectations: Question

Due to the challenging word choice, plethora of characters, and eventful plot there have been multiple occasions where as a reader you question the content of what you are reading, and become confused about what is going on. A specific question that I have relates to Pip and Biddy. On page 286 when Pip says ""... I reflected on what an unkindness, what and injury, what and injustice Biddy had done me." This quote was referring to the encounter Pip and Biddy had, in which they briefly discussed how Pip doesn't visit often. I was confused by this because Pip hadn't visited her on hardly any occasions before, so for him being frustrated at her for being skeptical of his word is strange in my opinion. I wasn't sure if it was maybe just because he has a bad attitude because of his rise in social standing, or is there was maybe a reason I failed to think of. Basically, I just think that Biddy definitely wasn't being rude or showing and injustice to Pip considering how he has acted lately in the book. It would be fantastic if someone could maybe further explain this particular quote.
