She didn't want to say she was scared. But, he had gotten close to doing some serious damage to her twice. And after a year, this is how he's welcome home? He did it for her, she knew but. Part of her still didn't know.
He felt like she didn't want to be with him anymore, that she was forcing it. Why? He did all of this for her. Why wouldn't she touch him? Love him? It made him angry.
She feared his anger more than anything. She had been disillusioned, she thought he would never forget her, and he had. Why couldn't she let that go? But he was always so angry that she was scared to bring it up.
