Yes. Sometimes I have trouble tossing something from a set even if it's broken. This is especially true of things like china, so I have a couple of very chipped teacups in our cabinets right now...I know they're not useful, but if I tossed them, I'd only have x number, when I should have y number, ykwim?
I've been working on getting past this and I have made progress. I've tossed all the broken china and crystal from the sets we have that belonged to my dh's family. The fact that there were so many chipped and broken pieces among that stuff made me feel better when I realized I'm not the only one with this fixation. It was easier to start by breaking up sets that weren't originally mine.
For the rest, I've begun to think about what a set really is. A set is a group of items that belong together because there is something that they have in common, typically use. But making sets is subjective. The sets of things for sale in shops have all been put together by someone who had a particular idea about what belonged together (and that idea was very likely motivated by the need to market and sell stuff.) But that person's idea of what belonged in a set might not apply to my needs/situation. I've decided that I don't have to agree with other people's ideas of what a set should be, and that I can make my own sets that may be smaller. I remind myself of this whenever I come across something I don't need but is part of a set and I find that it helps.
