Yes, it is entirely normal for the time it takes to move on from a past relationship to vary significantly from person to person. Emotional healing and the process of moving on are highly individual and depend on various factors, such as the depth of the relationship, the emotional investment, the reasons for the breakup, and one's coping mechanisms.
A 3-month relationship may seem short to some people, but it can still have a profound impact on your emotions and life, especially if you had strong feelings for the person involved. Additionally, the quality of the relationship and the emotional connection you experienced during those 3 months can influence how long it takes to move on.
Some people may find it easier to move on quickly, while others might take much longer. The key is to give yourself the time and space you need to heal and process your emotions. Don't compare your healing process to others or feel pressured by societal expectations. Healing and moving on are personal journeys, and it's essential to be patient with yourself during this time.
If you find that you're having difficulty moving on or that your emotions are significantly affecting your daily life, it could be helpful to talk to friends, family, or even a therapist to provide support and guidance through the healing process. Remember, there's no set timeline for moving on, and it's okay to take as much time as you need to find emotional closure and move forward.
