Upset about call

My hubby went to a friend’s surprise bday last night. Earlier I was a little moody due to the fact that he does that all the time giving short notices to programs he had to attend alone. But i got over it and even asked why he was still at home at 7:30pm when he said the party was to start at that time. He said the bday boy’s flight had delayed due to heavy downpours so he wasn’t sure it was coming on. Around 7:45pm he dressed up and said he still had to go just Incase the the party would come on. We have 3 children the first 10 years and the last 4 years. The kids and I were watching television together in our room and we all fell asleep. I’m a rather light sleeper and woke up around 1:30 am and released hubby wasn’t home. He normally comes home before 12 midnight if he goes out so I was a little worried. I called he’s cell phone several times and he didn’t pick and checked the last time he was active on ‘waz up’ and it was around 11:45pm so that really got me worried because he’s a phone addict...always online. I decided to call his close friend a guy who normally hangs with him only for the friend to say he’s not too well so he didn’t attend the party. His friend said he’ll try and contact one or two people who attended the party and check on him for me. After a while hubby calls and says he’s cell phone was on silent mode so he didn’t see the calls. A sigh of relief for me. He comes home around 2 :30 and starts asking why I called his friend, and that he’s a grown man so I shouldn’t do that again all upset. Really, what did I do wrong, why should he be upset for showing concern about his whereabouts, I just kept my cool because I was glad he was home safe and didn’t want to wake the kids. I’ve been quiet the whole day today hoping he’ll bring it up for me to tell him my peace of mind. He’s a good husband and father but I thought he went overboard last nite. He turned 40 last week so I’m guessing mid life crisis. I think I’ll let this one pass....
