It's challenging to determine the exact motives and intentions behind someone's actions without direct communication or knowing more about the specific situation. However, there could be several reasons why this person is liking posts or pictures of you even after choosing another girl over you:
Remnants of Past Feelings: The person may still have some feelings for you or have nostalgia associated with your past relationship.
Regret or Guilt: They might feel regret or guilt about their decision to choose someone else over you, and liking your posts could be a way of expressing this.
Attention-Seeking: Liking your posts might be a way for them to get your attention or elicit a response from you.
Keeping Options Open: They might be trying to keep a connection with you in case things don't work out with the other girl.
Insecurity: Liking your posts could be a way for them to boost their own ego or reassure themselves that you still care about them.
Unresolved Feelings: They may be unsure about their feelings for either of you and are trying to figure things out.
Habitual Behavior: Liking posts might have become a habit, and they may not necessarily attach significant meaning to it.
Regardless of their reasons, it's essential to focus on your well-being and emotional health. If their actions are causing you distress or confusion, consider limiting your exposure to their online presence or even unfollowing or blocking them if necessary. It's crucial to move forward and invest your time and energy in relationships that are supportive and mutually fulfilling. If you find it challenging to cope with these feelings, talking to a close friend or a mental health professional can be helpful in gaining perspective and finding ways to heal and move on.
