just got off the phone to my friend who has had a bit of a bombshell dropped on her by her new DP.
bit of a back story: he has a DS, 9 from his previous marriage which split up few months ago. and he sees his ds every weekend. my friend has not met his DS yet. she has known her DP a couple of years through work but they have only been dating 3 months. he had told her about his DS right from when they first met. my friend is a single mum to a 5 year old DD. its been going really well, i have met him and he seems nice and they seem really happy.
however last night he told her that his XW also has 2 older DS aged 12 and 18 (from a previous relationship), so basically, he has stepDC. he was with his ex from when the youngest was a baby so basically he brought the stepDC up, although they have always had a relationship with their bio dad. he has not seen them since he and their mum split up other than if they are in when he picks his DS up. apparently the stepDC are not interested in seeing him 
but up to them i suppose.
she says she doesn't really know what to think about it. i am just 
that he kept his stepDC secret for so long, especially as they have known eachother for a long time before they got together, why has he never told her before, i just find it really weird why tell her about his bio DS but not say anything about the other kids?? my DH is stepdad to my older DC and if he tells anyone about his family he always says we have 2 kids. (ie mine and his, and mine iyswim)
i have major alarm bells but don't know what to say to her as i don't know if i am over reacting, AIBU, or is he BU (and WEIRD) or maybe i just feel strongly as i am part of a step family...
