Advice needed-
My partner and I are planning on moving in together in the next year . He has a 6 year old son who we have gradually introduced to my children, spending more time together and they get on very well. He has him for 1 night every other weekend and a few extra days in school holidays. His ex , who he separated from when the child was a baby has for some reason been very difficult about the whole thing.
The latest situation is that his son had a sleepover at my house last weekend , obviously with his dad there too. He shared a room (bunkbeds) with my 11 year old which is our plan for when we move in together as I only have a 3 bedroom house.
His ex has massively kicked off about this saying he is not permitted to stay here as it is not cohering to his 'requirements for personal space' . She says she won't allow any other sleepovers or for him to stay here unless he has his own room . Does she have a leg to stand on ? They do have a child arrangement order but there's nothing on that saying he can't share a room .
I'm worried this is going to stop us being able to live together if she starts to withhold contact.
For reference, the ex moved three hours away from our area years ago, is married to someone else and the child actually shares a room with his half sister full time.
