You get distracted
Texting takes our attention away. Reading the message and then replying makes us forget that we are with someone else around. If that’s your man and he needs your attention, ignore the messages that keep coming on your device. Check them later on.
Men dislike being ignored
Be polite and caring. Respond to your man’s messages. Talk to him and tell him that if you cannot reply very soon it means you are busy at work and not because his message is not important. Even a short text can help you avoid conflicts related to this.
