Feeling emotional about past relationships, even after a significant amount of time has passed, is not uncommon. There can be several reasons why you still cry when thinking about your online ex-boyfriend:
Emotional Attachment: During the three months you were together, you likely developed a genuine emotional connection with your ex-boyfriend. The bond and memories you created may still hold emotional weight, making it difficult to completely let go.
Unresolved Feelings: If the breakup was sudden or you didn't have a chance to properly address your emotions, you might still have unresolved feelings about the relationship. These unresolved feelings can resurface when you think about your ex.
Nostalgia: Memories can be bittersweet, and nostalgia may evoke strong emotions. Thinking about the past can bring back happy memories but also remind you of what you've lost.
Loneliness or Missing the Connection: If you haven't found a new romantic partner or have been feeling lonely, you may long for the emotional connection you once had with your ex-boyfriend.
Comparisons: You could be comparing your current life or relationships to the time when you were with your ex-boyfriend, leading to feelings of sadness or regret.
Closure: Sometimes, closure is essential to fully move on from a past relationship. If you haven't had the chance to discuss your feelings, say goodbye, or get proper closure, it can leave an emotional gap.
Growth and Change: If the breakup was a significant turning point in your life, it may bring up emotions related to personal growth and the changes that followed the relationship.
Idealization: Over time, you might have idealized the relationship or your ex-boyfriend, forgetting the negative aspects. Remembering only the positive aspects can make it harder to move on.
If you find that these emotions are significantly affecting your daily life or well-being, it might be helpful to consider seeking support from friends, family, or a therapist. Talking through your feelings and experiences with a professional can provide you with valuable insights and coping strategies to process your emotions and move forward. Remember, healing from a past relationship takes time, and it's okay to feel sad or emotional. Be patient with yourself and give yourself the space to heal and grow.
