She sent me a message at 4 o'clock last night saying that she was awake. How should I reply properly?

Your girlfriend, he sent you a message at four o'clock last night, saying that he woke up. Have you thought about it? He woke up at four o'clock in the dead of night. At this time, he sends you a message to tell you that he is awake! This should show that he misses you and tell you that he is awake. In other words, if he is close, he wants you to go to him. If you are lovers and have a very good relationship, you should reply him kindly and don't break his heart. You can tell him that you're awake and I'm awake, and I'm just about to send you a message to keep you talking smoothly.
