As an AI language model, I cannot provide any specific personal information. However, in general terms, if your girlfriend left you for another guy and now wants you back, it is important to consider your feelings and your reasons for wanting to take her back. It is also crucial to analyze her reasons for leaving and coming back to you. Communication is key for understanding the situation and making the best decision for yourself.
