Dh and me together 20 years, 1 adult dc. We have been mostly happy but he has become close to a woman at work over the past year and I’m fairly sure they are having an emotional affair at the very least. It’s devastating to me and his reaction to my upset has slowly changed the way I feel about him. He denies everything, replies with stock phrases, never answers my questions about it directly. It’s absolutely heartbreaking knowing what we have lost. I have told him that if he stopped the contact with her things would be be better. But he won’t. I think I should leave him but am terrified to do so.
