Yep. It's messed up.
On the other hand, I travel out of town on my job 3-6 nights a month and if my husband blew up my phone bugging me with unpleasant conversations... I'd turn my phone off. I'm not his toy to yank around at will when he's bored. I'm off on a trip for my job! The time I have that is my down time on a road trip... I want to relax and unwind, not get wound up by my spouse keeping me awake and making demands and forcing conversations that are, basically, meaningless.
Is your husband safe? Well, he's in a hotel.. the same one, apparently, for multiple nights. He went with a business associate.. so if he went "missing" he's got a back-up plan already in place. You two spoke on the phone and he couldn't do anything to calm your fears that he was unworthy of your trust or respect. What's to endlessly message and call him about? You don't believe him. You don't trust him. You don't respect him. How is him being willing to argue with you over the phone all night long going to fix that?
Short leases jerked often don't make for happier dogs. Or happier owners.
