Sorry to hear that, man. Of course you're not going to be rational about it, it's not the type of thing you ever truly move on from, just learn to live with.This one hits hard and it's difficult to reply. I would dare to say NO, it's not selfish to have a child instead of adopting, but what do I know? I've been raising my nephews for 5 years, a pair of twins that aren't my own. I've been doing so because my brother (their father) has been imprisoned during that time for a crime he didn't commit. So yeah, I basically raised someone else's kids and I did my best.
But also, it hits hard because I know what it's like to be told "you are going to be a dad" by the woman of my life only to be told later she's lost our baby before it was even born, due to a natural miscarriage. I'm not going to lie, I was scared, but something deep inside me also wanted that, I wanted to have that baby with the woman I loved, I wanted that life, I was looking forward to it and I wanted it so badly, then it was gone. I know I'm talking from an emotional, non-rational point of view but that's how I was feeling back then. After that, things deteriorated quickly between us, and she even tried to kill herself, in the end, we broke out, and I've never been the same after that.
I had an idea that I wouldn't be able to raise a child that wasn't mine before, but I was sure of it once my cousin passed away from cancer and left behind my niece. All of the sudden there was a real possibility that I would have to care for my niece if no one else could and my immediate thought was panic. My aunt ended up taking care of her but this whole situation scared the hypocrisy out of me.
