Quiet rage

So.  I'm on holiday. I work long hours.  On the other hand, hubsy is at home all week except Monday and Friday when he works.  The rest of the days he's at home with two wee girls. I get quiet rage when he goes out.    I know it's unreasonable... I know he needs to get some man time, I know all the benefits it brings to our relationship for us to have a bit space...for his own mental health etc... so why do I get the silent rage whenever I get the text that says 'I'm off out after work for a few hours'?  Is it that I think he should spend all of his time with me?  Am I really that wife?
