ya thts true ...u shud have been told....but may be your parents thought tht u ll hate her more if they told tht to u at a very young age....any way ,past is past and now u shud get out of it and talk abt it openly to your sister...tht ll help u out a lot ....and relieve u too.....

Yeah. Go talk to your sister. And tell how you feel. Maybe that will make you feel better.

Look at it this way, after having grown up with her, you can now continue the relationship, HOWEVER had you have been told before, you would have been immediatly hostile.

that must be a chock but ur relation between ur sister and u stay the same after after this news maybe that ur relation will be stronger than before ...she`s still here with u thats the most important!!

Your parents should tell it before for sure but there was maybe a good reason or that... but if you love her as you said so nothing can change this!!As Ashley said, maybe that your relation will be more stronger than before!She's not your biological sister but in you heart she will always stay the same..never break this...

wat difference does it make to u to learn that she is ur half sis?does that affect the way u love her? did it ever happen that u feel a certain strong bond to a total stranger ... n u really respect n like that person like yr own sis or bro???then if u say u really like yr sis , no matter if she's yr own or nt shouldnt bother u!!!!!! b happy that u have her, so many dnt have anybody that close in their families..
