no one wanted to tell me until it was over

i was talking to my bmom this weekend. we have been in conact since i was 14 and i had found my aunt by fluke because she was friends with my ex-bfs grandma and lived in the same building( my first name is very original). i knew my bfamily when i was younger before i was taken away at 4 nad my bmom decided to tell me that my grandfather died a week and a half ago. of course after the funeral and memorial nad everything was said and done. she said she would sen me the program from the funearl as if it would make up for it. i wanted a "real" family my whole life. i wanted grandparents(i never had themn the foster homes) i dont know what to feel. i want to cry but dont know if i should. i should say that i do not know if i have the right to feel the sorrow since i did not know him for the majority of my life. i am angry though. i know that for sure.
