Your post reminds me of a short story I once read. Please don't take this as a personal judgement on you or your marriage; it's just a lovely story I thought I'd share.
I can not remember the author, but the story was entitled "Doors." It was about a newlywed couple who had a great loving wonderful marriage. However, the wife grew up in a house that shut and locked doors, whereas the husband lived in the type of household that was so close-knit they didn't even close the door when using the bathroom. They had both emigrated to America, India I think but I can't remember.
Often, the husband teased her when she closed the door behind her and locked it to take a shower. She couldn't explain why--she had just always done that.
One day, the husband's cousin shows up to "visit" unannounced. The wife graciously offers him the spare bedroom, but the cousin insists upon sleeping in the livingroom--on the floor--in the center of the house so that the family can be close together. Months pass like this. The cousin is loud, invasive, and often just walks into their bedroom unannounced. He does not keep order in the livingroom.
The husband doesn't mind this. It's how he grew up; his cousin is family; he believes in sharing the house as a family. The wife does not agree. She has a studio in which she likes to work alone from home, and this is the one door she is allowed to close. Still, the noise from this cousin affects her ability to work, to sleep, to relax. Her friends notice the change in her, and worry for her.
One day, in her office, the door is closed and she is trying to take a moment of peace for herself. The cousin opens the door without knocking, not caring that he interrupted, and asks her for the tape (something else, but let's assume tape since I can't remember). The wife snaps. She throws the tape at him and screams for him to get out of her office, and then proceeds to slam and lock the door in his face.
The husband is unhappy with her. And they have an argument. At the end, she retreats to the bedroom. She hears a door close, and she's not sure if she'd closed it in an angry blur as she stormed face-first towards the mattress, or if someone else had closed it for her.
