After breaking up, I texted my ex-boyfriend, but he ignored me and hurt me. Is it embarrassing?

You want to know the truth? Then I tell you, the first reply is that you are polite, and the second reply is that you are annoying you. Do you have a boyfriend who needs to talk to him? Does this have anything to do with him? Do you want to hint at him with the stimulus of "I still feel pain without you"? Since he chose to break up, this message is just a waste of time for him, so it is right to say that you are bored. If you are still thinking about the old mutual affection, just say something, don't cut yourself short.
