Fortunately, it wasn't strange for husbands to act that way toward their wives. Most of them saw their wives as their property. Because of that, they would do anything to make sure no one else touched what they believed belonged to them.
In the past, some men who went to war even forced their wives to wear chastity belts because they were afraid their wives would cheat. That dark period caused many women to suffer infections, and some of them even died because of it.
Even though people no longer do things that extreme, the mindset hasn't fully disappeared. Some men still ask others to keep an eye on their wives whenever they go out. If a wife disappears without telling anyone, she might even be punished.
Well, Edmund also always kept an eye on her, and… yeah, it was borderline obsessive. But at least he wouldn't do anything if Primrose deliberately covered her tracks or didn't wear her ring.
