I don't reply to the breakup message sent by my boyfriend.

If you sent a breakup message to your boyfriend, he didn't reply to you or delete your WeChat. Then I think he may be busy with other things and have no time to watch the news on his mobile phone. So I haven't replied to you. This is the first possibility. The second possibility is that he saw you. You sent him a message saying that you broke up with him. Now he must be thinking about how to reply to you. Or thinking about how to keep you, he may be thinking about how to send a long message. Then pray for your forgiveness, or pray for your return.
