Not sure if I can answer your questions, but I would like to share a little of my own experience.

I am similar to you in the way I feel my way through life rather than think my way through it. I often felt if I could only find someone on my level to share it with, how much more meaning our relationship would have.
Then it happened, about 16 years ago I met someone who seemed to feel what I felt, see how I saw we clicked on a really intense level.
Only problem was we got lost in each other, and when things went wrong there was no balance both our emotions were so intense we couldn't even come close to seeing the others perspective. When it was good it was amazing for us. Although everything else got locked out of our little world...even our kids to an extent we were so entwined we made damaging decisions to stay in the same level.
When it went wrong it was horrendously volatile. We hurt each other in ways no other person could have.

We had 8 years of absolute bliss, then two years that ended with him trying to kill me.

I am not saying this is how it always goes, but I will say that being so similar was definitely detrimental when it came to trying to fix things, because we could see no alternative than the way we felt.

I would say embrace those differences, because they could be the very thing that saves you from the rough times. Having an alternative perspective can often be an excellent thing.
Don't mistake his inability to "get it" with him not appreciating your way of seeing things.

In an ideal world we want someone to get us without us having to explain.
But sometimes being forced to explain helps us,examine our thoughts and perceptions, and that can definitely be a good thing.

I hope you manage to work things out because it's sounds like a good thing you have going. All the best.
