My 7 year old Dd has a much older half brother (30) she's never met because her dad hasn't had contact with his son since he was born,my ex told me about his son after we met so I was aware there was a son living locally.Saw a photo on sm about 8 years ago.
Anyhow a new girl started in Dds class last year and they get on well but this last fortnight they have been attached at the hip and in this time her friend has been to our house twice and met up in local park with friends mum also.Her 2nd visit to ours today she was picked up by her stepdad.
It's my Dds brother!!!!
I was a bit shocked but obviously couldn't say anything as he's totally unaware as far as I know.
My Aibu is this,do I mention this to friends mum (brothers partner),my ex has said his son knows who he is,but ex is a pathological liar so who knows.
Dds brother was raised by his stepdad from birth.
It's not like I expect them to have a sibling relationship because of the age gap but feel awkward having this knowledge and not sharing it,i also don't want to mess up Dds friendship as she finds it hard to make connections.
WWYD?
YABU-keep quiet
YANBU-Tell the partner I think he's Dds brother
