Your sincere and heartfelt admission that you did wrong may not make things right, but it will go a long way towards mending a broken trust. The Venus/Neptune trine on October 15th, followed by its last sextile to Pluto at the 29th degree of Capricorn on October 17th, says that this isn't the time to hold back or to hold out. If you truly want a second chance, then you need to be bold and ask for it. There's no guarantee that you will get what you want, but the fact that you are willing to open yourself up to rejection speaks more about your recent emotional growth than any amount of promises to do better in the future. Perhaps the reason why forgiveness remains one of the tallest orders of the Universe is because it requires such human vulnerability and humility—from both the person asking for it and the one granting it. This is what makes forgiveness the rarest miracle of all.
