Well, the way OP tells it, she kind of uprooted her life as she knew it to move and be with him.
I'm not saying it's right of her to be stuck on the breh like that ... but I kind of get it.
That said, he tries to include her when he goes and does shyt. That's basically all you can ask of him.
Considering that OP says he enjoys the time he spends with her and doesn't get tired of her (though he wants space to do his thing, understandably so)... it doesn't seem like there's much of a dilemma to address. Why make a mountain out of a molehill?
I somewhat agree with this
If the little exchanges you have about not being around 24/7 aren't that bad, it might be tolerable
Get married, she’ll be asking for space in no time
but I fully agree with this too
and then when you have kids, it's all downhill from there
