Knowing how to tell if someone likes you should be simple enough but it can be difficult to read someone's signals. There are a few ways to tell if someone likes you without coming right out and asking.
1 Body language - When someone likes you, they tend to lean in toward you during conversations. They also may put their hand on you or brush against you.
2 Another way to tell if someone likes you is to watch their eyes. Are they focused on you? Do you often catch them staring and when you meet their gaze, they hold it for a few seconds then look away? This could be a sign that they're interested.
3 When someone likes you, they may do things just to be closer to you. They'll take lunch at the same time, sit at the same table or offer to work with you on a project. You'll find that they may go out of their way just to spend time with you.
