The most immediate signs of affection portrayed by a man are evident in his body language and physical gestures.
Eye contact from across a room that lasts for longer than one second is a surefire way to tell that a man has a crush on you. If you initiate eye contact with a man and he glances back at you a second time, his interest in you is high. If a man interacts with you with an open posture and arms relaxed, he is comfortable around you and would like to get to know you on a deeper level. If he draws particularly close to you or lightly touches you on the shoulder from time to time, he is deeply physically attracted to you.
Word of Mouth
If the opportunity arises for you to meet a man's friends and family, pay attention to their reactions.
A man who has a crush on you will converse about you in a positive manner when you are not around. If a friend of his makes a comment upon meeting you such as, "So you're the girl I have been hearing so much about," he is definitely pursuing more than friendship with you. It is a huge plus if he invites you to meet his friends and family, as these are steps toward a commitment. Another sign that a man has a crush on you is if he talks about you to your friends. If you leave the room during a social gathering with your friends and he asks them questions about you or pays you compliments behind your back, he knows that the information will get back to you and has a deep desire for you to recognize his strong feelings of attraction toward you.
During conversation, is the man you like nodding in affirmation, smiling and agreeing with you? In addition to adequate eye contact, actively engaging in conversation signifies a deeper interest than if he were merely talking to a friend or acquaintance.
His interest level is also shown by asking personal questions centered on your likes and dislikes, then making a point to remember your answers later. If he performs considerate actions, such as opening the door for you or taking your hand to help you down the steps, he is attempting to make you feel comfortable and happy around him. Performing one or more of these considerate actions signifies that a man has genuine feelings for you.
