Conflicting travel styles?

Recently retired couple in our mid sixties. I have always been the one to plan our travel itineraries and my partner is a freewheeler (his words). He will get up in the morning with no idea what we could do for the day - he likes to let it unfold. This includes figuring out how to get places (again, which are unknown at that point). Frankly, I’m burnt out and would now like to book tours, if only to save my mental health. He is unhappy with that because of the structure of the tour travel.

Anyone out there feeling my pain?

Update! Thanks everyone for your input. I think that I need to do what’s best for me at least half the time and leave the freewheeling to my partner. I’ll join him in his adventures (or non-adventures) if I feel like it, and if I don’t, I’ll do my own thing those days. I really appreciate your input!
