If your ex-boyfriend still thinks about you even after breaking up with you due to lying caused by another girl, it could indicate several things:
Lingering Feelings: Despite the breakup and the reason behind it, he may still have feelings for you. Emotions don't always disappear immediately after a relationship ends, especially if it was meaningful or if there was a strong connection.
Guilt or Regret: He might feel guilty about the way the relationship ended, particularly if he was involved with another girl during the breakup. Regret over past decisions and actions can lead to thoughts about the person he hurt.
Nostalgia: Memories of the time you spent together can evoke feelings of nostalgia, leading him to think about you and the moments you shared.
Unresolved Issues: If the breakup was a result of lying caused by another girl, there might be unresolved feelings or issues that he hasn't fully processed yet. He might be contemplating the past to make sense of what happened and understand his emotions better.
Comparison: It's possible that he compares his current situation with the memories of the relationship he had with you. This can lead to thoughts about you, particularly if he feels unsatisfied or uncertain about his current circumstances.
Interest in Reconciliation: In some cases, thinking about an ex-partner could be a sign that he is considering the possibility of getting back together. However, it's crucial not to assume this without further communication and understanding his intentions clearly.
Regardless of the reasons, it's essential to focus on your own healing and well-being after a breakup. While his thoughts about you may be intriguing, dwelling on them may not necessarily be healthy for you emotionally. If you both still care for each other and believe there is a chance for reconciliation, open and honest communication might be a path to explore. However, it's crucial to assess if getting back together would be in your best interest and if the trust issues from the past can be effectively resolved. Take your time to make decisions that prioritize your happiness and emotional health.
