Is it ok is a crush lasts for more then 4 months?

Yes, it's perfectly normal for a crush to last more than four months. Feelings can develop and evolve over time, and a prolonged crush might indicate a deeper connection or attraction. However, it's important to assess whether the feelings are reciprocated and to consider moving forward, whether that's expressing your feelings or finding closure if necessary. Ultimately, every situation is unique, and there's no set timeline for emotions.
