Hi brokenentity, it might just be that the trust has been knocked (??), but that doesn't mean that it can't be built back up. Maybe give it a bit of time for them to realize that it's not going to happen again, if it isn't??, or ask for their help to see that it doesn't happen again?? But I'm taking it that you need their forgiveness more than their understanding, did you??
Kind of hard to know if I'm near the mark without some more details though, if you could tell us a little more???
