Really not sure about this. I divorced him after 24 years marriage for unreasonable behaviour. I won't give details as not really relevant.
Despite the grounds we have managed to have a non acrimonious divorce and split finances fairly. We are on friendly terms and have a 9 year old in common (kinship care, we're too old to be parents) who he sees reasonably regularly.
When we split he bought a campervan to live in (he had enough money to buy a small house or decent size flat in our village without a mortgage and his pension is intact)
Because he lives in a campervan he's been using my address (former marital home, I bought him out) for everything - including online deliveries and his vehicles are also registered here.
I've told him I'd like him to stop this and make other arrangements by the end of June. He came today for his post and said it's proving impossible
I'm struggling to explain why I mind, it's about moving on, I think (I'm not seeing anyone btw). But I know it's difficult for him.
So IABU, no skin off my nose really compared with the difficulty for him
IANBU, how I feel is actually quite normal and his choices are his responsibility.
I'm so undecided I will probably go with the majority view.
