Body language often shows a person's true feelings and, if you know how to read it, can indicate that someone doesn't like you. Watch to see if the person turns his head when you speak, shifts his body away from you or begins to do something else, such as check his phone, when you're around. The person's facial expressions can also reveal that he's not interested in your presence or what you have to say. Note if he frowns, looks elsewhere or rolls his eyes.

If the person begins to spend less time around you, it's a possible sign that she doesn't enjoy being in your company. For example, if she stops showing up to events that you attend, such as a regular party or sporting event, she might not like you. A decision to cancel her involvement in one-on-one activities or decline invitations can also reveal her feelings. Note, however, that a friend who misses one event doesn't necessarily dislike you; watch for trends to emerge, rather than concern yourself with a single act.

Failing to initiate contact, either through an email, phone call or a suggestion of getting together, can show you that someone doesn't like you. If you find yourself as the one who always gets in touch -- or notice that the person used to get in touch but no longer does -- it's possible that he doesn't like you. Additionally, when he or she consistently declining your offers of getting together with weak-seeming excuses such as, "I'm busy" or "Sorry, I can't make it" are also signs.

How the person dialogues with you can indicate her lack of interest in having you as a friend or a partner. Note the frequency with which she uses flippant remarks such as, "Yeah, whatever" or "I dunno" during conversations, or she simply ignores what you say or responds in a manner that indicates she wasn't listening. The person might also use condescending or hurtful phrases, such as telling you she doesn't care what you say, openly insulting you or talking negatively about you to others in your circle of friends.
