Was

How long would it take to forget someone or something? Four months, four years, four decades?

I can't remmber the both of you, anymore.
I just knew there was something, something different, something good and something painful.
But all of those were merely objective fragments of my memory. A dictate of hippocampus. A pronounced fact of the past.

I dont know who you are. Why I felt that way and why it faded away.
Selective retrograde amnesia. There are people who unconciously forget things (and others attached to it) in order to regain themselves and build continuity. It can be a total loss of previous memories but in some cases certain parts are selectively deleted.
Feedback mechanism for self preservation.

I don't know really. I'm just wondering....
