My ex-girlfriend sent a holiday greeting message. How should I reply?

To tell the truth, two words: Happy New Year. no need to say any more Please cherish your handwriting.

Looks like you still like her. That's a real pity. Your wife is ugly, which only shows that you have a bad relationship with her.

You are a man. Text back and you won't die. Why save face?

Show it to who? You deleted her, and she called you, which means she feels guilty. You just need to reply a message.
