I screwed up

I messed up, I made a really bad decision and I hurt the person I love the most, my EJ. I broke her heart and I have no idea how to fix it. All I know is more then likely she will never trust me or even love me the same ever again. We are too very different people, I love openly and am quick to forgive the wrongs done to me. EJ is very skeptical about love and doesn't give her heart away freely. She has a very hard time forgiving especially if she trusted you. I knew this about her yet I made that horrible decision to betray her trust. I don't know what to do now, I have told her how much I love her and how sorry I am... I am use to being the one getting hurt, not the one causing the pain. I have seen EJ cry before but I have never been the cause of the tears..and when I saw those tears falling down because of what I did, I hated myself. I felt like someone punched me in the stomach. Is there anything you can do when you've betrayed someones trust other then wait? Cause if so I'm open to suggestions. I've been sending up prayers to God for the last two days to help me make this right..I just can't believe how stupid I was.
