One possible theme could be obsession. Since it's about a wife stalker, the stalker is likely to be obsessed with the wife. This obsession can drive the plot and create a sense of tension and unease throughout the story.

Another sign is over - monitoring. In many stalker friend stories, you can see that the stalker friend constantly checks your social media, texts you too often, and seems to always know what you are doing. For example, if you post a photo on Instagram and within seconds they comment with details about where you are or what you were thinking when you took the photo. It's a bit scary.
Perhaps it's a neighbor who has some sort of mental illness. They might have developed an obsession with the main character for no clear reason. They see the person through the window and start to stalk them, seeing them as an object of their strange fixation.

They might be casing the place for a robbery, but their presence in the window makes them seem more like a stalker.
One common theme could be the unrequited love aspect. The stalker character might be in love with someone who doesn't initially reciprocate. Another theme might be the element of mystery, as the stalker's actions and motives can be a mystery to the other characters.
