Am I being dramatic or unreasonable?

Last night my bf and I started playing Minecraft together and on his past map, it was named after his ex and so I asked him to delete it. He told me he did but looked at me funny and said he doesn’t care but it was a weird thing for me to care about. I get everyone has a past but I don’t really like to see it. Am I being unreasonable?
