What if my boyfriend sends me a message and doesn't reply in time?

It doesn't matter if you don't reply in time before seeing it. If you are busy, your mobile phone is not with you. You reply to him afterwards and explain the situation to him, and your boyfriend won't blame you. If you don't reply to him in time for something important, he may be angry with you and ignore you. You have to explain to him that you are really busy. If he loves you very much, he won't mind On the contrary, if you don't reply, he will understand that anger is temporary. If he doesn't love you very much, he may blame you. In a word, your boyfriend loves you very much, and he won't mind if you don't answer him.
