Should he call if he is going to be late.

So my boyfriend and I live together. No we aren’t engaged yet. We are 23 years old. So he works at a restaurant and a couple of times he does get hole late. But he doesn’t call of text me if he gets home late. He gets off from work close to midnight. Then, like almost an hour has passed and he doesn’t call of text me that he will be getting home late. Now im a type of person that worries. Especially since it’s dark and he don’t live in a safe city neither where a lot of crimes, stealing, and killing goes on. Since I’m his girlfriend and not his wife. Will it be wrong for me to tell him to either call of text me when he be home late. I’m trying not to call him too much because I don’t want to be like his mom. So what is the best thing to do?
