There could be several reasons why someone who doesn't like you might try to be your friend:
Social pressure: In some social situations, people may feel obligated to be friendly or act like friends with others, even if they don't genuinely like them. They might do this to avoid conflict or awkwardness within a group or community.
Manipulation: Sometimes, individuals might try to befriend others they don't like as part of a manipulative strategy. They could have ulterior motives, such as using the relationship to gain something from you, exploit your kindness, or spread rumors about you.
Insecurity: Some people who don't like you might try to befriend you out of insecurity or jealousy. They may feel threatened by you or perceive you as a rival, and trying to befriend you could be their way of keeping an eye on you or trying to bring you down.
Curiosity: In certain cases, someone might try to befriend you despite not liking you because they are curious about you or your life. They might want to know more about you or get closer to you to understand you better.
Changing opinions: People's feelings and opinions can change over time. It's possible that someone who initially didn't like you might start to see different sides of your personality or actions, leading them to reconsider their stance and try to befriend you.
Personal growth: Sometimes, individuals might recognize their own biases or prejudices and make an effort to overcome them. They might try to be your friend as a way of challenging their own negative perceptions and growing as a person.
It's essential to be cautious and observant in such situations. If you feel that someone who initially didn't like you is trying to befriend you, take the time to understand their motives and intentions. Trust your instincts and remember that healthy friendships are built on mutual respect, trust, and genuine liking for one another. If you sense any manipulation or negative intentions, it's okay to set boundaries and distance yourself from such individuals.
