Hello people
I just want your opinion about my situation. I had a boyfriend, but he knew another girl and then he decided to broke up with me. I realized of that girl because, he used to chat with her. After that we did not have communication around one year, but in my birthday he sent me a message mentioning my qualities. Why did he do it? Why does he do it. if he broke up my heart and decided to stay with another girl? How to answer to his message?
