Wendy was taken aback and attempted to say something, but failed, twice.
She had been aware of that long before Alan said it out, but she dared not to reveal it... it might ruin his self-esteem.
She couldn't bear to see Alan get hurt.
"I know you don't really feel happy with me. I tried to make you happy. I tried to offer you the best I could. But I always fail. It seems beyond me." Having got it off his chest, Alan felt much better. He went on, "Therefore, I think we should just... break up."
He dreaded to hear the two words, either from his mouth or hers, and he avoided any contact with her, afraid it might stir yet another conflict.
Now he realized it was good for nobody.
Since they didn't belong to each other and a break-up is inevitable, he reckoned an earlier one would do both of them some good.
"Alan..." Wendy stood there with a lump in her throat and tried to fight back tears.
