Nothing you said OP shows your partner is controlling, which is a question you asked at the beginning, I just don’t feel there is enough information for any of us to judge or give a good opinion. So with the books, you could keep the couple that are sentimental, being clear to him that they are, and ditch the rest, the dried spices, well they do lose flavour, I clear ours out sometimes as well, and there was the clothes you took in, just get them sorted, shouldn’t take long. I feel, possibly wrongly, that you wanted everyone to say he is controlling so you feel ok about keeping lots of things, but again, not enough examples in your posts on how much stuff we are talking, is there more or is it just the books? Il project a bit, my partner has way too many clothes, 80% at least never worn, they go musty, get moved about, sorted, vacuum packed, fat clothes, thin clothes, but never actually thrown out, I gently encourage him to throw/donate them, but he never does. I’d never throw them of course, but just a thought that your partner may be thinking similar, or maybe not, give some more examples if you can.
