Honestly before asking whether or not you should try and get back with her, ask your self this..can you really trust her again? and do you really sincerely love her and want to spend the rest of your life with her? If you want to try to work things out simply because of the way you guys felt about each other in the past...it's really not worth it. However if you really love her and think that you'll be able to work on your trust issues then give it a shot...good luck!
