I broke up with my boyfriend, but occasionally I send him a message, and he will answer me why?

It's simple. Even if we break up, there is no need to die of old age. We can still be friends, right? Besides, he may still have you in his heart, so he is still paying attention to you. He will still help you if you have something, so he keeps your contact information and phone number. If you want to get it back, it should be easy. Think for yourself. If you are not going to make up, there is no need to contact him often. If he has a new girlfriend, it will be really bad for all of you, and there will be a lot of trouble, misunderstanding and so on, which will be more troublesome. Be decisive when you part.
