I don't want to have kids because I don't want to lose my son.

I'm 23M, I have an 11 year old brother who passed away a year ago in an accident that was no one's fault, it was just an unfortunate result of circumstances. it completely tore my family apart, and no one will ever be the same. he was everyone's best friend. Ever since then I just know that I don't have it in me to risk losing another boy like that. He was the greatest little brother in the world. I know that this is a hard stance to have, when I get serious with someone down the line, I'll break up with them over this. I don't care. It's better than having to laugh through the tears as I watch my hypothetical son graduate from high school.<br><br>Edit: thank you all so much for your kind words, advice, and support. I'm reading through everything, and I really do appreciate all of it.
