How do you not remember the names of everybody who was in your fifth grade class? You went to school with them all every day for months! Same thing. Tony Stark interacts with a lot of people in his life, and from his POV, Mary Jane and even Peter wouldn’t have been so important or life-changing that he’d necessarily remember everything about them years later.

I dunno I think I would remember someone who lived with me, I had different room mates in my life and I still remember them all, I mean living with a person is kind of a pretty big deal.

Also this makes Tony sound like a douche but I am not surprised if that was the intention.

The sad thing is, he rather make Tony look like an giant asshole than blame it on “One More Day”
