My ex broke up with me a week ago because his feelings were not growing for me. While he was breaking up I wanted to meet and talk to him to clear things. He refused to meet, was rude and spoke minimum. He said he would contact me later when he feels comfortable. He texted after a week he broke up. The text which he sent was "yes". I don't know if I should reply to him or just ignore this message. Should I respond or not?
