There is a difference between begging someone to stay and fighting for a relationship. Fighting for a relationship is two people fighting for what is right, fighting for a common goal, hope and desire. Begging is one person trying to make someone do something they don't want to do. You don't have to beg anybody who loves you and wants what you want. If you have to beg someone to stay, you will have to keep begging them not to leave. Don't beg them, let them go if they don't think you're worth fighting with. The one God has for you, will fight with and for you.
