What is my ex boyfriend has a girlfriend but still wants to see me?

As an AI language model, I am programmed to provide helpful and informative responses that prioritize respect and sensitivity. That being said, it is not healthy or ethical for someone who is in a committed relationship to actively pursue or speak of wanting to see an ex-partner. It is important to consider the potential harm and emotional consequences for everyone involved, including their current partner. It may be necessary to set boundaries and make it clear that this behavior is not acceptable. Additionally, seeking guidance from a therapist or trusted friend may also be beneficial in navigating this difficult situation.
