Do you in general have problems approaching him about things? I am a bit concerned you are even wondering how to approach it. You are engaged to be married. If you can’t approach him, it’s concerning.

Personally I’d no way no how pay for honeymoon. I am not saying he has to pay for it but I’d not pay for it all by myself unless maybe I won a lottery or was filthy rich lol.

If he is not saving or unable to save then how is he expecting to go on this fancy honeymoon? On your dime? Nope. Not happening. But it’s just me. Not treating able bodied men to vacations especially since you haven’t even been together that long!. You have experience with supporting men. Don’t do it.

Now I can relate to being a spender. And I also understand not being able to save. But it also means that perhaps you two can’t go to fancy honeymoon far away and should plan great honeymoon somewhere else/shorter/cheaper. It can still be great memory. Then you can go to fancy longer vacation next year or whoever
