sounds kinda like my wife. She is usually pretty understanding. but every once in awhile she gets upset. and i simply remind her that i hunted before i'm gonna hunt after i got married and she is the one that said yes. I warned her when we started dating that when deer season rolls around that she probably wouldn't see much of me.
She didn't even get mad at me last night when i decided to go hunting rather than trick or treating. (only cause i saw a shooter 2 days earlier)
Just sit her down and explain to her. Don't yell. Then she cant see the passion you employ for the sport. I'm sure she has something that she loves that you hate.
My wife loves teddy bears. So much that i let her spend $300 on a little bear she was wanting. But guess what i get to hunt pretty much whenever I want.
But even if you get to that point that doesn't mean you take advantage of it. You still have to use some judgement. and spend some "quality" time with her.
