To understand how it concerns you in fact - it is a problem which concerns people for a long time. Not everyone shows the feelings so that it is easy to interpret them. Happens and so that the person tells one, and itself thinks absolutely differently, hoping to achieve deception something.
Look in eyes
Pay attention to how the person looks at you. Very little who will be able "to forge" a look. If it is adjusted openly and friendly, then you will understand it at once even if the person is laconic. Eyes will tell you everything about his true feelings much quicker, than any words and compliments. Even if he is confused and cannot be at the correct loss for words, then on how he looks at you, it will not be reflected in any way.
Sometimes the person sympathizes with you, but it is afraid to express. He can look at you, but is afraid to meet the eyes of you. Try to look aside, and then unexpectedly raise eyes. If he watches you, then will not manage to look away.
"Read" its gestures
People cannot usually control the gestures if only they did not work on it specially. Even in this case very few people manage it. Gestures express the position of the person, they point to his emotional perception of events. When the person is ready friendly and openly in relation to you, he as though reveals. Socks of its footwear are turned to you, he as though is developed to all of you by a body. When the interlocutor "is closed" and is not sincere, he crosses hands and legs, is subconsciously closed from you by hands, instinctively turns away. When the man waits for your attention, all his body as though signals about it. Its case "is opened" to you, it can begin to copy your gestures, to correct a belt or a hairstyle.
Communication
It is important how the person communicates with you. If you are pleasant to him, he concerns you with attention, does not interrupt, listens to your position on any question. If he scornfully behaves, then think whether really the sympathy from its party takes place? If you guess concerning his sincere opinion on you, try to find out from mutual friends as he speaks of you. Quite often on this sign it is possible to understand a lot of things.
You already together
Happens that the girl guesses what true attitude towards her of his young man when they already together. In this case just have with it a heart-to-heart talk. It is not necessary to finger it with questions: "And you love me?" or "What do you think of me?". Create the confidential atmosphere in which he will relax and will be more open. Then it is possible to start a conversation about what disturbs you in its relation and forces to doubt it. Do not forget that quite often men are more constrained in manifestation of feelings, than women.
