This isn't an AIBU as such, more a What Would You Do?
I was at my sister's house earlier and she showed me something on her phone from a whatsapp group. When I glanced at the name of the chat and the people in it at the top I realised it contained the members of my family (the ones who have a phone) apart from me and my family (me, husband and child).
So that's 2 sisters, 2 brothers, a sister in law, a brother in law, niece, nephew and my mother in a group.
Back story - I don't speak to my older sister and she very much rules the roost in the family.
I left her house feeling quite down and left out (I have spoken to my mother about this before but she says I am oversensitive.)
WWYD in this situation?
