Sad with husband

​I felt really hurt today.
​My husband took today off as a leave day to go to the pub with his mates for the Cup, a big horse race in Australia.
​The funny thing is last week I asked when his next days off are so I could book my 12 week scan and he told me next Monday which is his planned day off. He neglected to tell me he had today and tomorrow as holiday days. 
​I got angry at him today, most of the day he's not answering him phone. 
​It's out of character, maybe it's the baby coming which he has desperately wanted and asked about btw but I'm just worried..
And I don't like the guy he's apparently gone to the pub with, I think he's bad news.
