What does it mean to be able to send distressed messages?

I think maybe his mood is quite complicated. First of all, you are his girlfriend. Sending him such a short message is actually enough to express several meanings. The first layer is that you love his busyness and hard work; The second layer is that you know the nature of his work; The third layer is because I didn't understand him before, so I feel a little guilty now. In fact, your boyfriend should have understood how you feel. Secondly, he actually loves you, so he is not angry because of your previous inconsideration. On the contrary, he is glad that you can express your change of attitude towards him through SMS, so he accepted your concern lightly. Thirdly, he said that every industry is not easy. In fact, he also wants you not to feel too guilty. After all, it is not easy to live in this world, so he doesn't want to emphasize this difficulty too much. A man is also a proud existence, so he should have understood your meaning and your mind. Don't feel guilty, just care more about him.
