YANBU. It would piss me off too!
A little bit of courtesy goes a long way. It's like I don't mind DH staying out/staying away, but at least have the courtesy to keep me updated on where you are, and what time you will be back.
DH used to have a habit (slightly different to this,) of getting up early Saturday or Sunday, and going off out, not leaving a note, not taking his phone, and then just waltzing in anything from one to three hours after I got up.
I didn't mind/care if he was out all DAY, but he could have at least let me know where he was and what time he'd be back! It used to fuck me off big time. I thought 'where IS he? What time will he be back? Have I got time to clean the house, watch a film, catch up on the week's recorded TV programmes I have???' It was annoying, and it felt like a form of control to me at the time (maybe an overreaction I dunno!)
It felt like a form of control, because he was swanning off out, with NO note, or any clue where he was, or when he would be back, so I was sitting there on tenterhooks not able to relax, or settle into a movie, or just generally enjoy the time to myself. So it felt like he was sabotaging the chance for me to enjoy the time alone.
I used to complain, but he said 'I didn't know I had to have my wife keep tabs on me.'
I said 'it's just common courtesy FFS. Let me know where you have gone and what time you'll be back.' He said 'what if I don't know what time I'll be back?!' I said 'well at least keep your phone on you so I can contact you if need be. OR if you plan on being 2 hours away and end up being delayed by another 1 or 2 hours, you can let me know. It's just common fucking courtesy!'
He doesn't do it now, after this one time I played him at his own game. He was out when I got up, and had not left a note or ANY form of contact to say where he was or when he would be back. 2 hours after I got up, he STILL wasn't back. So I got dressed and got my house keys and bag, and got the bus to the train station and got a train (at midday) to the city 30 miles away. I switched my phone off.
I stayed there all afternoon and even got myself an early evening meal, and got the 6.30pm train back, and finally got in at 7.30pm. He was standing at the door and said 'where the fuck have YOU been? I have been texting and ringing you since 2pm!'
'I have been ringing round your friends and family and we've all been worried sick!'
I said 'I just felt like fucking off for hours on end and not letting you know where I was - or when I would be back!'
Ya know, like YOU do every other fucking week!'
He glared at me, walked off in a huff, and then said 'ok point taken.' 
All I ask is to be kept in the loop and to know what time he will be back. Is it too much to ask?!
As I say, he stopped doing it after this, and it was some 20 years ago when he was more immature and thoughtless!
And yeah, calling someone UNHINGED is fucking nasty. And usually comes from the worst kind of people.
Hope he is home now OP!
