My boyfriend's ex-girlfriend sent him a message, and her boyfriend returned. Basically, I have to send it back. I found it by accident. What should I do?

In fact, there is nothing to be wronged. Your boyfriend probably just can't pull his face down. He was embarrassed to refuse, but he had no feelings, otherwise he wouldn't say they were impossible. Your boyfriend doesn't allow you to return messages to your ex-girlfriend, but you can always find out who it is, right? Then you can create an opportunity to let her know that he has a new girlfriend and give up. If you don't give up, well, you are famous for everything. Therefore, the most important thing is to let his ex-girlfriend know that he has a girlfriend now. You can't let your boyfriend think that you are too deliberate, so there is basically no problem. If your boyfriend takes the initiative to find someone else, break up early or use some tricks to get him to meet.
