Son is 9 and his father and I split when he was small. We have managed to co-parent together in a mostly amicable fashion, but things have been rocky lately.
Sons father lives a lifestyle that involves a lot of mud. He doesn't live in a house, but in a community of people that live in yurts etc. They're all constantly in wellies because as soon as it rains it gets super muddy.
School has lent son a trumpet as he wishes to learn. The problem is that every time he takes it to school from his dads, the case is absolutely filthy, as it gets put down by muddy wellied feet in the car or van on the school run. If it comes back to me before he takes it to school, I do my best to clean it, but the case is textured and the mud gets into the crevices and it always looks dirty.
I find this mortifying. It's an expensive instrument and it isn't ours. I feel it's our duty to take good care of it and I worry our son also finds it mortifying to take it to school so filthy.
I have suggested to his father that it stay at my house where it can be kept clean and our son didn't take it to his. I confessed I found it embarrassing and worried our son felt the same. He went mad and said I was "disgusting" and "holding our son back in order to score points".
Our son doesn't even seem that interested in the thing and never voluntarily practices. It's not as though he'd miss it dreadfully if it didn't go to his fathers house. But his fathers words have really landed and I'm struggling.
Thoughts?
