Hi M.,
With all due respect, there's not a whole lot to go on here. I will say this, not knowing your ages, you may be having reactions to well established behaviors due to possible hormone, or other physical, changes. I'd schedule a physical and have them do a hormone work up on you. I'm not suggesting the answer is drugs but that information may reveal why you've turned this corner.
My second response is to sit him down and talk to him. Men are especially bad, forgive the generalization, at picking up on signals and reading our minds. So how can you expect the situation to change if you don't discuss it with him. Boys tend to be very concrete so you need to sit him down from a place of love and be very specific when asking what you need from him. What he needs to change or at least be sensitive to.
Lastly, to your last point, I would sit him down and google some travel ideas/locations over a cup of coffee or a glass of wine and see if anything sparks his interest. I hate road trips so we tend to fly for vacations but there's no wrong way to do it as long as you're both excited about the journey and the destination. Good men are hard to find and marriages are not 50/50, they're 100/100. Give him some loving patience and some time to turn another corner.
Good luck!! :-) S.
