She has to under stand your passion, just as you do hers. If she doesn't understand how important hunting is to you then you need to let her know.
Resume'.....I was single for 39 years and married the greatest lady in the world. There's a reason I was single that many years....and it doesn't mean "they" were always the problem.

I'm glad I met Lisa when I did. I wasn't "ready" for a LADY such as her as a younger man.
My question would be.....Was she excited for you RE: the original dates of the trip? Was she genuinely excited FOR you? If so....I don't see how adding a day to a wonderful trip would bother her so?????
My wife understands the things other than her I hold dear. She doesn't prey on me and use those to her advantage, though. BUT.....when she calls....I come running. When she asks....I drop everything and do for/with her. It's a trump card used sparingly, though....and I NEVER begrudge her for playing it. This morning I'm going over to my in-laws to put up their new storm door. I'll do so, gladly....in lieu of hunting, this morning. She asked. I'll jump.
If you ever saw the movie 'Phenomenon'....you'll recall the scene when John Travolta's character was buying up his love interest's (Kyra Sedgewick)chairs she was making....even though they weren't the greatest chairs in the world (he bought them all,anonymously,and stored them up in his shed). He bought them because he wanted her to feel good about herself.....and because it helped her out, financially. There was a scene later in the movie where Robert Duvall's character was telling someone about it......and he asked another guy in the movie if he'd ever "bought his wife's chairs". It was a great, POWERFULline....and I've never forgotten it.
I "Buy Lisa's chairs" whenever I can. She needs to buy yours, now.

Understand what makes her tick.....and do things for her out of love. If she doesn't return the sentiment....I'd say you may not have found "the one". I wouldn't be surprised if that's true at 23. I'm not sure many are ready for the whole "chair" reference at that age. I know I wasn't.
Good luck to you.
Oh yeah.....The preacher is a smart man.
