We've been divorced for most of 9yo DC1's life. exH is an alcoholic who lives overseas with occasional email contact only. He pays nothing for DC1, bought a christmas present for the first time in 2019, and has generally never shown interest in the practicalities of DC1's life.
DC1 has an activity they love and wanted to get some training with other kids in a group setting. There's several local providers, with one being locally more "famous" and expensive than the others. There were forms to fill in, a practical assessment, and then a waiting list. In one of the early forms they asked for the names of both parents and I filled this section in with background explanation that I was a single parent, that exH lived abroad and did not have contact, and that I would be solely responsible for paying the fees.
Today they've offered a place to DC. However, they addressed the letter to both exH and I at my address. This is the 4th time this has happened in correspondence and I have corrected it and explained the situation every single time. The third time I also explained how unpleasant it felt to receive mail addressed to exH at my address.
I now feel like turning the place down and going somewhere further afield, or to a less well-known club even though it would be inconvenient for me and maybe disappointing for DC. I'm half beginning to wonder if someone is doing this deliberately. If that's the case, I really don't want to be dealing with this admin team for the next few years.
