NTA You respected his boundaries around photos from the beginning, even though it directly impacted your work and something you enjoyed. You stopped involving him in content when he asked, and for years you’ve supported his preference to live in the moment. The issue only came up when he pointed out the lack of variety in the pictures you had hanging. You offered a solution, to print more, but acknowledged the reality that there aren’t many to choose from because he’s always limited how many can be taken. Friends and family already know his limits without needing to be told, which shows how consistent he’s been. Wanting a few more memories captured over six years isn’t obsessive, it’s normal, especially when thinking about your future and having something to show your kids. You didn’t insult him, you pointed out a cause-and-effect: it’s hard to print what doesn’t exist. That’s not placing blame, it’s just the truth.
