On a first date, people often focus on attraction and miss subtle behavior issues that only show up with time. Dating experts say a person’s true character usually appears after about three months, when habits like poor listening, lack of empathy, or selfishness become harder to hide. At that point, it’s important to decide whether these traits are minor flaws that can improve or deeper red flags that could damage the relationship long-term.
Experts list common unattractive qualities such as poor communication, constant negativity, lack of kindness, selfishness, sarcasm, one-upping, lying, jealousy, flakiness, and lack of ambition. While some behaviors can change with effort, others are often ingrained. The key is recognizing whether a partner is willing and able to grow — because ignoring red flags early can lead to bigger problems later.
