He drove the highway at night. I called him for a while, and then suddenly it broke down. I texted him to drive well, and he didn't call me.

I think you are unreasonable. I didn't talk to you when I was online. Maybe I just hung up. Or busy, once but not many times. You say that to prove that you don't trust others. You know people are on the highway. Maybe you didn't see it when you were texting while driving. I'll text you or call you later. That's nothing. To put it mildly, you care too much about him, and he doesn't give you enough sense of security. To put it mildly, you are unreasonable.
