How to tell each other that I am not his good marriage?

I didn't marry you. Marriage means a happy marriage, which usually describes the person you like. If you feel that the other person is not your own marriage, you can directly express your attitude and thoughts and say "I am not married to you". Good marriage, a word and noun of China, comes from "National color is hard to meet, good marriage is no longer" in "Two Orders in the Building" by Li Yu in Qing Dynasty.
