I can understand why you'd be surprised she said hate so strongly. When I or others try to show you the depth of the hurt you caused you get angry and call it shaming. Then you're surprised she could say she hates you.
Look at your signature again. Look at how much of her relationship with you you spent cheating. How could you possibly be surprised she'd say she hates you?
