You can immediately understand whether you like it or not, but when it comes to love, everything becomes more complicated. As a rule, you will intuitively feel how you are treated, but there are several non-verbal signals that give a person's feelings.
People look at people they like and avoid eye contact with people they don’t like. During eye contact, neurochemical processes occur in the body, the level of oxytocin increases, which increases mutual attractiveness, and also affects pupil dilation. The stronger the expansion, the more people are drawn to each other.
People often try to touch the person they like. This light touch is not an invitation to bed, it just shows strong sympathy. Men express their sympathy for other men, striking with their fists or lightly striking the other person on the shoulder, so the stronger sex demonstrates its respect, recognition and hint of further friendship. Touches are a good indicator that a person loves or does not love you. If you carelessly touch the other person, and he, in turn, is sharply removed, this means that the person does not love you or is not ready for a more intimate relationship.
Body orientation is an important indicator that the person you are talking to loves you. People lean toward people they like, and they move away from people they don’t like. For example, if two people are sitting next to each other, then first their heads turn to each other. Then their shoulders will turn to each other. After that, their torsos will turn completely towards each other. Finally, two people will look at each other, leaning forward slightly to be closer. This is a clear expression of sympathy, which is expressed in body language.
People who love, reflect the position of each other's bodies. Mirroring is an unconscious action of the body. You, as if, repeat the movement for your beloved person. He can fold his arms, turn on his side or cross his legs, and you repeat this movement in a few seconds, and without realizing it.
When a person likes someone, he tries to remove all the "obstacles" that separate them. If you sit on the couch, he will try to get rid of such things as pillows, cups, bags, to sit closer to you. And if a person is unpleasant to you, then you will do the opposite, create as many barriers as possible, just not to come together.
