Two weeks after we broke up, I sent him a text message. I didn't reply.

Maybe he really wants to give up and break up with you completely, so he won't reply to your message, or maybe he deliberately abolished you so that you can take the initiative to admit your mistake. I hope you won't mention the breakup again.

Everyone's love situation is different and their personality is different, so the way of doing things is different. If you don't contact for two weeks, the other party will definitely feel uncomfortable. At this time, the active and reconciled party will definitely be at a disadvantage in later life, so it is unwilling to take the initiative.

If the breakup is really caused by your own impulse, then give in first and let the other party have a chance to step down. Of course, the premise is that the other party can't let you go completely, and they are still thinking about you.
