He didn't tell me because he was afraid of me?

I think you are a sensitive person ... In fact, he doesn't think it is necessary to talk about it at all. You know, he just checked your cell phone. You didn't say it unintentionally when you said that your mobile phone was in arrears, and his answer was unintentional ... Many times it's natural for us to talk and do things, and we haven't thought about how special something is, so we should tell someone ... relax, and don't always think that he was rude to you on purpose ... He didn't say it intentionally.
