DP and I have been together a year. My DC are 16 & 21 and I've been sleeping lot from their dad for 7 years this summer.
DP dc are 10 & 13 but he's only been split from their mum for 18 months. He moved out, rented for a year and now has his own house so they've had quite a bit of up heaval. His exw knows me & him are together and my kids do too (though they've not met him yet). I'm just wondering when we should let his kids know (I don't mean meet them, just that they know their dad is seeing someone)
