Sorry for the long post just need some outside input to know if I'm being unreasonable. ..
My partner has two kids (17 and 19) I have 4 (16, 13,11,3) moved in with my kids to partners house he owns about 8-9 months ago.
His 17 year old loves with us full time and has an outbuilding converted into his bedroom. My 16year old has a bedroom, my 11 year old has another and my 3 and 13 year old share the last room (which used to be his 19 year olds room - she moved to Scotland with her mum)
19 year old has come down to visit a couple of times and both times she has had her 'old room' back and my 13 and 3 year old have moved to sofa / in with siblings... She is coming down for 3 weeks over Christmas and partner thinks I'm being unreasonable because I said she can sleep on sofa first 3 nights until kids finish school... Then 16 year old go on sofa and she can have that room for the next week. After that 13 and 3 year old go to their dad's on boxing day So she can have her old room back.
He thinks I'm being selfish and she should have that room whole time and shouldnt be made to sleep on sofa 3 nights.
Am I being unreasonable??? I feel like this is a fair adjustment but it's causing a massive argument.
