I lurk on a blog for people who have been cheated on (married people and people who had/have a partner with questionable behaviour that could indicate cheating or a hidden other life, etc. I’ve only been cheated on once, that I know of, and while it was very painful - the guy also got arrogant and discarded me cruelly, saying he couldn’t believe I actually thought we’d been dating. It’s funny looking back because there’s nothing else you could have called it! - I know it pales in comparison to a marriage being broken up by similar means), and the things your husband said that you wrote in your post, I’ve read a hundred times over in the comments section. “I never loved you”, etc. It’s like cheaters come out of a factory.
This will probably sound harsh, but he was likely never the person you thought he was. I’m so sorry you’re going through this, because it’s all on him. You were the faithful, loving and above all, authentic one, be proud of yourself for that at least.
