When people have a crush, they often act nervous, giddy, or awkward, becoming more attentive, initiating contact, finding excuses to be near the person, and remembering small details about them, while also potentially becoming jealous or overly complimentary as they try to get noticed and build a connection. Behaviors range from shyness and increased eye contact to trying to impress them or becoming distracted, as the brain experiences excitement and stress.
Signs You Have A Crush On Someone
The "3-month rule" for a crush suggests waiting around 90 days to see if the initial intense infatuation (honeymoon phase) settles, revealing the person's true character, compatibility, and whether they're serious about a real relationship, making it a trial period to decide on commitment or moving on. It helps gauge consistency and emotional safety after the "spark" fades, identifying potential red flags like love-bombing or toxicity, though experts note it's a guideline, not a rigid rule, as deeper connection takes time and varies.
With all that going on, having a crush can often give you a sense of intense euphoria and giddiness that makes you feel bonded to someone (even if you barely know them) and maybe a little obsessed with them, Dr. Cacioppo explains.
Statistically, crushes often last a few months.
Most of the time, the feelings just…go away, but on rare occasions, a crush is returned and develops into a relationship. Some crushes have been known to last more than a year—but usually, they fade after you get to know the person a little better.

Key takeaways

Therefore, if someone has a crush on you, they may exhibit high arousal responses like blushing or nervousness when you are around. However, we must avoid overinterpreting someone's emotions. The person could feel nervous or uneasy for various reasons, not necessarily because they have a crush.
Red flags in a guy often point to controlling, disrespectful, or emotionally immature behavior, including excessive jealousy, love bombing, poor communication (like the silent treatment or name-calling), lack of accountability, disrespect towards service staff, and a pattern of bad-mouthing exes, indicating potential issues with empathy, boundaries, and personal responsibility that signal unhealthy relationship dynamics.
