1. Whatever you do, you seem to upset your partner
When someone really likes you, they will try to understand all the annoying little quirks you might have. They tend to concentrate more on everything they like about you, not on the things that are usually irritating. But things change when your partner doesn’t find you attractive anymore. That’s because it’s in people’s nature to observe and comment on a lot of subjects when they find something they disagree with.
If your partner doesn’t like you as much as they used to, they will start to be annoyed by many things you do.
