Hi
I think in my head I've turned a bit of a non-issue into an issue, so looking for some advice and context!
DSD has not got on with her StepDad for the last 2 years - her Mum & StepDad have been together for 8 years (married for 5), I've been with DH for 9 years so neither of our relationships are new.
Following lots of very heated rows and disagreements (mainly between DSD and her StepDad), DSD (14) was dropped off at ours last October with a bag of clothes and has been here very since. She saw her Mum twice for a few hours over Christmas but other than that there has been very little contact from her Mum and DSD has not been back home at all. My DSS (15) is still living with his Mum and StepDad and gets on with his StepDad so no issues there plus he's still visiting EOW and school holidays (when his social life doesn't get in the way!).
I have a reasonably good relationship with their Mum. We've had to discuss a few things about DSS recently but when I've broached the subject of DSD she shuts down and avoids it and hasn't responded to my messages. DSD has not seen her Mum since Boxing Day - 6 weeks today. I really feel for her and she won't talk about it so that's another issue on its own.
DH says it's very straight forward and DSD is now living here, which is fine but is it really that easy? I want to start the ball rolling in formalising DSD living here (tell school, change Dr etc) but surely her Mum needs to agree to this and how do I do that if she won't deal with it? What do I put in a text, letter or voicemail to her. We're still paying child support for both children so that needs to be recalculated to include just DSS but I don't want to do that out of the blue - and I don't want to go ahead and make the changes if their Mum doesn't actually see this as a permanent situation..... Grateful for your advice.
