Good for you. I know it feels good when nothing is a secret anymore.
Truth be told I didn't hold anything back from my husband on D-Day. He knew everything. Although I did back at the beginning of the year tell my husband the gruesome details about the A. Like sex stuff. Because he wanted to know. Telling him that was the hardest thing I ever told him, but honestly I think it was worth it because I feel like it helped him heal a bit. I know that he is "over" this at all and won't be for a long time. But I feel like telling him helped him.
I know it was probably a really hard thing to do, and you should be happy you did. At least now you know that your BS knows everything. This A will probably hurt her for the rest of her life because it was something that the love of her life did to her. She will heal and things will get better.
Just keep up the good work in your healing and you will get through this. It is a long road but it is possible.
