Ex-boyfriend is going to be a soldier. I want to send a message to care about it, but I don't know what to say.

Here are some things you can refer to, hoping to help you:

1. Congratulations on starting a new life journey. I know this is a growth and challenge for you. In the army, you will have more opportunities to develop and improve yourself. I'm proud of you.

Please remember that no matter where you are, I will care about your safety and happiness. I hope you can get more growth in the army and show your courage and wisdom.

In the army, you will have the opportunity to make friends with a group of real soldiers and comrades. Please cherish this opportunity to be a better person and don't forget to contact me often.

Please pay attention to your health and don't overwork. In the army, you need to pay more attention to diet and rest. If you have any difficulties, please don't hesitate to tell me in time.

I believe you will do well in the army and become a real hero. No matter what happens, I will always support you and wish you a bright future, peace and happiness.

Finally, remember to put your true feelings and worries in and express them in concise and sincere words. No matter how the relationship between you changes, your concern and blessing are a kind of support and encouragement to him.
