This person may be trying to subtly flirt with you: looking over frequently in the hopes of catching your eye. Two can play at this game! If your eyes meet, you can react in two ways: look away quickly, to play the coy role, or smile warmly to acknowledge the person.
Try touching back. If you like the way that it feels. If it feels electric, real, and right, don’t be afraid to reciprocate. This can be a great way to signal that you are attracted, too. [5] X Research source
Be aware that they are likely not only attracted to you. Even if this person has a crush on you, there’s a good chance that they encounter other attractive people. Don’t be discouraged just because there’s a bit of competition! Eventually, you might be able to distinguish this person’s “attraction” behavior from the way that they act around platonic friends. It may not be what you expect. Some people even clam up and get uncharacteristically shy around those whom they like!
For example, maybe they talk about sensual things or sensitive things. Maybe they are always asking you how you’re doing. It can be a hard thing to intellectualize – sometimes, you may find that you can feel a palpable energy between yourself and another person
Ask a friend, if you aren’t sure. If a friend of yours has seen the two of you together, he/she might be able to give an outsider’s perspective on whether the person is attracted to you. Make sure not to ask a mutual friend that might spill the beans![8] X Research source
Do not be forceful, and try not to make too many assumptions. Be respectful, always.
If this person is already in a relationship with someone else, they may have committed to monogamy. Consider whether it is your place to disturb that agreement. The person in question might not be looking for any sort of relationship, period. Know that your attitude toward attraction is not necessarily the same as everyone else’s attitude toward attraction.
