According to body language expert Tonya Reiman, "mirroring is just mimicking someone's behavior, whether it's their voice, their words, or their nonverbal clues (think gestures, movement, and body posture)." A person who mirrors you will likely be getting the message that you are comfortable with what is happening between them and you do not want it to continue. Mirroring can also mean that your partner is trying to get you into a confrontational situation where you will say something that you will later regret. If you are feeling confident, then your partner will reflect this by not arguing with you or pointing out your mistakes. But if you feel uneasy about a topic of conversation, then your partner will probably try to push you towards saying something that will make you look bad. Finally, mirroring can simply mean that you are agreeing with something that your partner says. If they comment on something that you have seen in the news or on social media, for example, then they will most likely mirror your reaction. This type of mirroring is very common among friends or family members who want to show support for each other. People use the term "mirror" when describing their partners because it is an accurate description. Your partner should not make you feel uncomfortable or unsafe. If they do, then you should find another partner who will behave properly.
