The receipt wasn't left lying around! It was in her study.
With the rest of her stuff (other than what's beside her bed).
Because she's already been trained by him to never leave anything laying around in communal areas else he'll throw it out.
She can't even leave treat food or drink in the fricking cupboard or fridge without him consuming it as fast as he can, to deprive her of it.
She doesn't live there. It's her registered address but she's barely tolerated and that tolerance doesn't extend to her owning stuff.
He's a bullying abusive arsehole who doesn't want a partner, he wants a slave he can control. For housework, sex, to provide him with children and nanny duties for all the bits of parenting he CBA with, to earn money to help pay the bills and maybe to entertain him when he's bored. Some kind of humanoid robot would do for him now the children are in existence, but nobody has invented one yet.
Although he might still go get a partner even if he had a robot, because so many of his type actually enjoy having someone else to stamp down on, their lives aren't complete without it.
I can't understand why people are justifying hoarding & think partners living in the same house should accept it as a character trait.
Because you know what someone is like before you marry them. Hoarding is hardly something a person can hide, it's physical stuff. You don't marry someone with the intention of changing them. If that's how you feel, that they'd have to change to be acceptable to you, then you're with the wrong person.
A hoarder doesn't merely hold on to a few unnecessary bits & pieces. They have a serious aversion to throwing away anything from worn out shoes to packaging. It must be a nightmare to suffer from this anxiety inducing affliction & equally difficult to live with.
Which hardly fits with OPs description of herself as someone who has continued consistently to minimise the amount of her personal possessions during this relationship. She also doesn't mention being unable to throw out worn-out shoes or packaging.
Not all hoarders hoard trash or have teetering pikes of junk, sometimes it's an excessive collection of ordinary things but all tidy, clean and in good condition. Nowhere has OP mentioned that they're living in squalor, with pest control issues or a fire hazard, for example.
I'll bet she's not a hoarder at all and has just been told this repeatedly during her marriage to the point he's got her believing it and blaming herself for his bad behaviour.
"Tidy" means different things to different people. The OP resides in this house too. She's accommodating her husband's preferences for minimalism in most of the house. She should be allowed some personal space to keep her own things how she wants to. Some people don't do well with the everything-hidden-away-in-a-cupboard style of organising.
OP I just finished up a bottle of peach schnapps I bought as a duty free treat on holiday in Greece... 10 years ago! I rarely drink, a few times a year is all. You know what my partner does if he wants a drink, which is maybe around once or twice a month? He goes to the store and buys one, if he's run out. He doesn't take mine.
