How to win a Saggitarius back—

Hello to everyone! I'm a Gemini in love with a Sagittarius man. We were together for almost 6 years and I got to a point where I was confused and decided to pursue someone else to find out for myself if I am really in love with this Saggitarius man. I don't know why I did what I did, but now I totally REGRET it and I need help.....I want my Sagittarius man back and I am willing to do anything and everything to prove to him that I love him and I want to make up for everything. He told me that he's afraid to ge hurt again. He said that is he takes me back, he's afraid that the same thing would happen again at some point in our relationship. PLEASE HELP ME. How can I convince him? What should I do?

Thank you!

My brother is a Sag and he had a kind of the same situatin happen to him. He's very stubborn and won't take anyone back who has hurt him, however...if you do a bit of coaxing he would probably consider. Sometimes if you write someone it helps as well, especially with guys because it registers better. They actually read the words and it sinks in. If you composed a really good letter and poured your heart out and told him that that's the last time you will bother him...you may get a response, but make it gooooood. If you need help let me know.
