Hi
God is forgiving. Its in the past. Its time to forgive yourself. You can not change the past... but you can change your thoughts and reaction to it. We humans don't understand much about anything. You must believe that anything that happened in the past was for a reason. A reason beyond human understanding. The only true problem now is your inner thoughts about it. God truely has forgiven you. Please find the space within yourself to forgive yourself. I forgive you.
If you continue to be unable to do this ... please talk to a therapist. Talk to a profession about this. (note; millions of other woman make the same choice, some have regrets also.) Its time to take a deep breath and come back home to the moment with a forgiving GOD. Best Wishes,
JC
