To me it sounds like his parents left him when he was young. here are some key points which make me think that:
All these memories distorted (indicate he was young and hard to remember)
You're discarding (they gave him up)
Granted existence (makes me think its of him being brought into this world. if not for this i might think it was a breakup)
The boy devoid of your nursery (he didnt get the typical life of a kid with his parents)
