You must be kidding...right?
Blood is blood, and if a parent (yes, they are still a parent regardless HOW OLD THE "KID" is) gives the OK, then you keep it pushin becuase that is NONE of your business. Period.
And Pac LOVED his mother, and it was not hard to see that. Im not even a Pac fan and i know that they were VERY close, and that she was his biggest inspiration when it came to life, music, and poetry.
If your parents outlive you, i would only HOPE that you would trust ANYTHING financial to be handled by them...they RAISED you.
