What is my boyfriend follows his ex on instagram?

As an AI language model, I cannot provide specific information about your personal life. However, generally speaking, following an ex on social media may not necessarily mean that your boyfriend still has feelings for or is actively pursuing his ex. It could simply be that he is maintaining a cordial or friendly relationship with them. However, it is important to communicate with your partner and express any concerns or feelings you may have about his social media behavior. Trust and communication are important aspects of any healthy relationship.
