There could be several reasons why your ex wants to be friends after breaking up with you and while being in a new relationship. Here are some possibilities:
Emotional Connection: Your ex may still value the emotional connection you had during the relationship and genuinely wants to maintain a friendship because they appreciate your presence in their life.
Guilt and Empathy: They might feel guilty about the breakup and want to offer friendship as a way to lessen the hurt they caused. They could also empathize with your feelings and want to be there for you in a different capacity.
Familiarity and Comfort: Being friends with an ex can provide a sense of familiarity and comfort, especially if they are going through significant changes in their life, such as starting a new relationship.
Shared Interests or Social Circle: If you and your ex share common interests or are part of the same social circle, they may want to maintain the friendship to avoid awkwardness or maintain group dynamics.
Ego Boost: Having an ex who still wants to be friends might boost their ego and reaffirm their desirability.
Keeping Options Open: In some cases, an ex might want to keep the door open for a potential future reconciliation, though it's essential to be cautious about such motivations.
Controlling the Narrative: By staying friends, your ex might want to control how the breakup is perceived by others, portraying themselves as amicable and kind-hearted.
Not Ready to Let Go Completely: Your ex might not be ready to sever all ties with you, and being friends can provide a way to hold on to some level of connection.
However, it's essential to approach this situation with caution and self-awareness. If being friends with your ex is causing you emotional pain or hindering your ability to move on, it's crucial to prioritize your own well-being. Sometimes, it's best to establish some distance and space to heal and gain clarity. Remember that it's okay to set boundaries and communicate your needs in any relationship, even with an ex.
Additionally, keep in mind that every individual and situation is unique, and the motivations behind your ex's desire to be friends may vary. If you feel confused or uncertain about their intentions, consider having an honest and open conversation to gain a better understanding of their perspective and to express your own feelings and boundaries.
