Why didn't my boyfriend answer my phone or return my text messages after the breakup?

No, you think too much. Think about it. As a man, breaking up with his girlfriend is uncomfortable both physically and mentally, so what he needs at this time is time to treat his pain, so you don't need to send him a text message at this time, really. Bad timing. It's not interesting to send it, do you think? But the only thing I can do now is to wait, wait for a while, and when he comes to his senses and puts everything down, then he will naturally have the courage to answer your phone or even send you a text message. Give him some time, don't worry. In other words, it's only a matter of time, do you understand? Forget it, okay? It is not good for you to think too much.
