"lack of a rounded perspective means he blows work issues out of proportion as they're his whole life"
Oh God yes, we've all worked with/had Managers that, that's true of. They're a pain in the arse.
OP, my DH was the same, but it started when I was a SAHM. I coped by having a life/going on holiday without him. It meant I didn't go to Venice/Florence etc, though.
It impacted on my ability to work.
We had lots of plans for what we were going to do in the future.
He had a Heart Attack, then bad health, then Cancer and died.
Is never get into a relationship with a workaholic, or even someone who doesn't value time together.
We wasted years. When you get onto your 50's, you realise how precious time is. You do experience things differently at different ages, have different energy levels.
In truth, you can't put things off. You've got to be honest and think, "we aren't doing that because of work" amd weigh up if thays what you really want, without future plans coming into it, unless they are within that year.
