What is my ex boyfriend wants me back but he has a girlfriend?

As an AI language model, I cannot provide any specific information about your ex-boyfriend as I do not have access to your personal life. However, in general, if your ex-boyfriend has a girlfriend but wants you back, it is important to consider your own feelings and the potential consequences of getting back with him. It is not fair to his current girlfriend or to yourself if he is not committed to her but still seeking a relationship with you. Communication and honesty are necessary in any relationship, so it may be helpful to have a frank conversation with him about his intentions and make a decision based on your own values and feelings.
