So my sister has a boyfriend and they are expecting a child together, due in May 2021. I haven't met the boyfriend yet ( they don't live close).
My sister, myself and my partner share a WhatsApp group with my mother where we exchange photos of our children and discuss daily matters.
Two days ago I added this boyfriend to our WhatsApp group in order to "welcome him to the family" before we get to meet in real life.
He thanked me for adding him to the group and I asked him if he was looking forward to being a dad and he said very much so.
Yesterday I discussed something with my mother in the group. It wasn't a lot of messages, maybe ten and they all occurred within an hour.
Later on there was a notification that my sister's boyfriend left the group.
AIBU to think this is rude? He could have muted the group.
I asked my sister why he left the group. She said she didn't know, but perhaps the messaging was too much for him.
This is hard to believe for me, because when my sister visited me, she was on her phone all the time WhatsApping with him.
