The first day I posted on this forum, I believe it was about 3 weeks before I had the info I needed to confront H about OW.
Make copies of your intel and keep it in a safe place. When my H realized I had hard copies of emails, he thoroughly looked until he found them (this was after I had confronted him about A). Luckily, I had screenshots saved in a folder on my computer too so I did not lose all of my intel.
And don't forget to GAL and take care of yourself.
