Patience and understanding go a long way (and some groveling)
Their are a lot of women with the question on their mind about how to get your ex boyfriend back. Well its not all rocket science really just be nice to him and make sure you apologize for what ever you did. If the break up was mutual then you both need to apologize but you starting would be a huge step in the right direction. If you have nothing to apologize for then why is it you that wants him back and not the other way around? Be humbled and realize that you made a mistake, admitting it is half the solution!
