What does the last text message of my boyfriend mean?

There is someone in everyone's heart who he cares about most. This person who cares most about himself may have left the deepest impression on himself. There should be a certain emotional imprint between two people, so should I. I have the message that we broke up in my mobile phone, and this short message is the last thing I want to delete. I still remember the content and sender of this short message.

The sender of this short message is my ex-boyfriend. Although he didn't directly express his intention to end this relationship and break up with me through the content of this short message, I can feel his helplessness through the content of this short message, because he and I are in a state of long-distance love, and it is impossible for us to have a final result. We are all enterprising people, and it is impossible to give up our career in order to achieve love.

In this case, he sent me a short message, the content is that I hope I can take good care of myself in the next days, remind me not to stay up late, be strong when I encounter difficulties in my workplace life, and wish me to find my own happiness and happiness in the next days. This is the last message my ex-boyfriend sent me. At that time, I only replied with a thank you. Since then, the two of us have never had any contact or intersection, but I can't let go of this relationship in my heart, and I can't bear to delete this short message, because it is the last mark he left me.
