What would you do?

My husband just found out he got the job he wanted but he didn't tell me. I found out via his text messages. He even told someone else instead of me! I also discovered (by reading between the lines) that he feels some type of way about the fact that I don't call him during the day. (I'm a stay at home mom to our 11 month old.) I explained that I don't know when is a good time for him to talk so I don't call unless I think he can talk....to which he responded by saying he's "good" ... I don't have to explain...it's not like he doesn't have other people to talk to. How should I handle this situation? I don't wanna tell him I know because I'd have to tell him HOW I know. What would you ladies do?
