When INFPs have a crush on someone, they often display a unique set of behaviors and characteristics. Here is a detailed description of how INFPs may act around their crush:

1. Shyness: INFPs tend to be naturally introverted and reserved, so when they have a crush, they may become even more shy and hesitant. They might find it challenging to express their feelings directly, often preferring to keep their emotions hidden.

2. Daydreaming: INFPs have a rich inner world, and when they have a crush, they often spend a lot of time daydreaming about their potential relationship. They may imagine various scenarios and possibilities, creating a romantic narrative in their minds.

3. Deep conversations: INFPs value deep connections and meaningful conversations. When they have a crush, they may seek opportunities to engage in profound discussions with their crush. They enjoy exploring their crush's thoughts, emotions, and beliefs, as well as sharing their own.

4. Thoughtful gestures: INFPs are known for their thoughtfulness and empathy. When they have a crush, they may express their feelings through small, meaningful gestures. They might remember their crush's favorite things, surprise them with thoughtful gifts, or offer support and encouragement when needed.

5. Nervousness: INFPs can become quite nervous and anxious around their crush. They may overthink their words and actions, worrying about making a good impression. This nervousness can sometimes lead to awkwardness or stumbling over their words.

6. Idealization: INFPs have a tendency to idealize their crushes, seeing them through rose-colored glasses. They may focus on their crush's positive qualities and overlook any flaws or imperfections. This idealization can make it challenging for them to approach their crush or see them as a regular person.

7. Creative expression: INFPs are often creative individuals who use various forms of self-expression to communicate their emotions. When they have a crush, they may channel their feelings into art, writing, or music. They might create poems, songs, or paintings as a way to express their affection.

8. Observant and attentive: INFPs are highly observant and pay close attention to the people they care about. When they have a crush, they may become even more attentive, noticing small details about their crush's behavior, preferences, and interests. They may use this information to connect on a deeper level.

9. Emotional intensity: INFPs experience emotions deeply, and when they have a crush, their emotions can become even more intense. They may feel a mix of excitement, nervousness, and happiness, which can sometimes be overwhelming for them.

10. Patience and hesitation: INFPs often take their time when it comes to romantic relationships. They may hesitate to make a move or confess their feelings, as they fear rejection or disrupting the existing dynamic. INFPs may need time to build trust and feel comfortable before taking the next step.

It's important to note that while these behaviors are common among INFPs, everyone is unique, and individual experiences may vary.
