Am I heartless


I haven’t had my biological dad in my life since I was 3 and I’ve found out today that he’s passed away, I feel bad but I didn’t even shed a tear, I just feel I can’t grieve for someone I never new, he was technically a stranger to me and never wanted anything to do with me. I am expecting a little boy in November and I’ve been told if my dad didn’t have a will I can claim inheritance although his wife would get the majority. I just feel he never gave me anything in life and i would like to see my son benefit from what I never got, am I wrong to feel this way?
