Jealousy can strike, from time to time, in a relationship, while at the office, or while scrolling through your social media feeds. Sometimes it can even happen when you weren't fully aware that jealousy was an issue. If your partner gets jealous on occasion, it can be easy to feel offended and think that they're overreacting for no reason at all; that the thing that made them feel jealous was completely random. There are some surprising ways you didn't realize you're making your partner jealous, however, which means that, while the situation might be completely innocent, their jealousy still might not be as random and out of the blue as you initially thought.
The real reason for their jealousy might be a reflection on them or a result of their past experiences, but that doesn't necessarily make it all that much easier for you to deal with the fallout that comes from doing something that you know wasn't something that they needed to be jealous about. Still, if you knew in advance that they were going to feel jealous about a night out with your friends or the fact that you had to work late, you might have been able to talk about it before it happened and maybe, just maybe, avoided the jealousy in the first place, or, at least, know how they might react. Just like you, they're only human, so knowing what you each might be doing to make the other jealous without even realizing it can be important information to know.
