It can be difficult to know for sure whether someone has a crush on you, as people often express their feelings in different ways. However, here are three signs that a woman may have a crush on you:

1. She seeks out your attention: If a woman is always trying to start conversations with you, or seems to go out of her way to be around you, it could be a sign that she has a crush on you. She may also try to make physical contact with you, such as touching your arm or shoulder.
2. She compliments you frequently: If a woman compliments you often, especially on your appearance or personality, it could be a sign that she is interested in you. She may also try to find common interests or similarities between the two of you.
3. She gets nervous around you: If you notice that a woman seems flustered or nervous when she is around you, it could be a sign that she has a crush on you. She may also avoid making eye contact, or seem to be at a loss for words when she is talking to you.
