What does the song "Don't talk about love" mean?

This song is about a man and a woman who met because of a heavy rain, and then the man fell in love with the woman, but the woman said that she still had an ex-boyfriend in her heart, and the shadow of the ex-boyfriend lingered, so the woman could not accept the feelings of the man at present. The man felt very distressed when he saw the woman's entanglement and embarrassment. He told the woman that it was all right. He couldn't talk about love, so he became friends first, and said that he would wait for her to get out of the last injury.
