I hope you're okay. My H had an EA too and he moved out of our home in January. The EA had ended by that point - but I don't think we repaired the damage at all and I don't think we ever addressed the reasons why he had the EA either. His actions were on him, but there were reasons he was in that place that I contributed to, and they were reasons we weren't able to repair things while he was living with me that I contributed to as well.
I have been been a terrible dark place but am feeling happier in myself these past few weeks and things are looking more hopeful in my situation too. Take a read of my threads if you think it would help.
For me, the biggest thing that has made a difference has been working to take care of my own emotional needs, working on my 180s, GAL and seeking the support of friends, and (important) setting clear boundaries about behaviour I will not tolerate from H. It's been a work in progress.
