I've just figured out something that I'm not sure how to handle. There's a long backstory but this gist is my partner has a DC from a previous relationship that isn't actually his biologically but very much is in every other sense, including the eyes of the law, as he had to fight extra hard for custody rights for DC when he broke up with their mum due to not being the bio dad. DC is now late teens.
The bio dad knows DC exists, and my partners very active role in their life but has never wanted anything to do with DC. The last contact was almost 10yrs ago when the bio dad bumped into DC and her mum and was apparently very clear that DC was not viewed as his child, and he had a new family now who didn't know about DC.
We've recently had a baby together and I've made very good friends with another mum through baby classes- lots of play dates outside of class, we text a lot, dinner/drinks without the kids. It's a lovely friendship I very much value as a new mum.
I've just twigged tonight that her partner is the bio dad.
I have no idea if she knows DC exists at all, and if she does if she knows that they're related to me.
Do I broach the subject at all? And if so how on earth do I bring that up?!
