I broke up with my ex-boyfriend for more than a month. I texted him recently, but he didn't reply. He didn't delete me on WeChat. What did he think?

Want to know what's going on, send some more. If he is still thinking about you, he is angry with you on purpose. You send a few messages, and he will definitely reply to you. Even if he doesn't reply then, he will come back tomorrow. Send a few and forget. Maybe he has slept with another woman and has no time to talk to you.
