You broke up with your boyfriend, and you changed your personal signature and online name to show your emotional state, or whether you are living well now, but it is normal for her boyfriend not to do so. He doesn't feel anything, and he doesn't want others to know his current state, how he is doing now, and he is not in the mood to publish and write.

We broke up, and we kept our feelings in our hearts. And maybe he's not used to changing his screen name, and he doesn't like changing his signature or making a statement. This is related to everyone's habits and personality. I think so, too, but he hasn't changed. He doesn't want to show his heart, and he doesn't want to come out and let others know. Feelings have broken up, and everyone has pain in their hearts.
