So I’ve just been on a big family holiday with my mum, brother, his partner, their kids, my sister and her family and me, my partner, my kids and my step daughter. On the holiday we did a number of family photos as due to distance we do not get together very often. One of the family photos was my mum with all the grandchildren, including my step daughter (who been in my life for 11 years, since she was 4). I’ve just discovered my sister and mum have edited the photo to remove my step daughter from it and then my mum posted it online. Am I unreasonable to be incredibly hurt by this?
