How do soldiers break up?

Personally, I think that a soldier always feels responsible, so he really won't break up on his own initiative, but he will be cold to you, choose silence, or make trouble without reason, and explain that he doesn't love you in various ways. He will make you unbearable and then ask you to break up, so that he will feel that he has not wronged you. He will feel better.

Soldiers, don't scold me. I have two friends who were soldiers. Both of them are like this.

I think it may be a coincidence, but I don't know what other soldiers are like.
