Hi Shawn, disappointing reaction from your niece... I do hope, without the FB publicity, you can sort the issues out... as there is no right and wrong in this...
Hugs and kisses to you... don't let it get you down too much... were you really close?
Family and close friends can react in very polar ways, some are un-phased, others get really Anti, the Anti ones, generally will come around, give them space and time...
L Katy
