[quote SlamLikeAGuitar]@findthecourage I can’t help on the guilt front, because I’m still struggling with that, even though I know it’s the right decision.
What I’ve done when DH has felt like he needs to say his piece, is to just let him talk until he’s finished, and don’t interject with any emotion no matter how hard that has been sometimes when I’ve felt white hot rage at the fucking audacity of some things he’s said 
I’ve almost conducted it like a business meeting

Yes, this!!!!! That is the only way. Do not let yourself be sucked into any kind of explaining. Say as little as possible, stay cool and collected.
I know that this is hard. I remember when I had "the talk" I just felt so bad, I felt this need to talk, to say something to explain, but at the same time, it felt so liberating to just sit there and say nothing. I cannot explain that but, for years, I was trying, mostly unsuccessfully to "work things out with my husband", but he would twist things to the point that I did not know what my point was. I would not know what I was trying to say or what point I was trying to make. Also, it would give no results. He would not listen, really listen, because he never thought he may be wrong. Things would always go back to being as they were. So right there that day, I gave myself permission to not say anything, to not explain myself. I literally told myself, "no, you do not owe him anything, you do not have to say anything, you can just do what you want, yes you can, how about that, this is what I want, I do not care that you do not understand, that you do not get it, that you did not think the things were that bad, it is not my fault that you were not listening to me over the years, that you did not care how I felt or what I wanted, so here, I want to separate, deal with it"!!!!
I am sorry, this may sound harsh but this is how I got through it. Did I feel guilty afterwards? Hell YES! It was eating me alive for months. He stayed in our house for three months and I literally thought I was going to die. Him moving out was the worst and a few weeks after he moved were still very, very hard.
But please listen to me, four months after he moved out, I feel so much better. Sure, every now and then I still feel anxiety creeping in, guilt and all kinds of painful emotions. But do I regret leaving him? No, not once. Just like @19Bears said, yes, I do feel relaxed in my own house, I sleep comfortably in my own bed. I personally am not thinking about new relationship, I am a bit older then you guys, I think, and all I want at this point is some peace and quiet. And I did get it, I do have it and it is delicious, yes, no other way to explain it. And my dear friends, you will have it too. Sooner or later this will all be a distant past and you will be enjoying your life, your money, your bed, and perhaps a new, better man, in peace and have an amazing life. Like I keep saying, it will get worse before it gets better, but get better it will.
Keep posting and hang on. You can do it!!!
