(((HUGS&TEARS))))
Please hang in there. We all make mistakes and have regrets. I don't know what happened but even if you did something bad doesn't make you a bad person. If you can make amends then do...if not then move forward. Failure is the most valuable of all lessens because it teaches us humility. You now will know what not to do.
On a personal note I just had my heart broken very cruelly...wish that he were more like you.
