(A little Adult Perspective)
Take it from someone whois aFather,Husband, Hunter and Musician.You were a hunter before a boyfriend. AsI was before a Husband.If she cant respect your desicion to hunt, then theres no future. Dont give up hunting because of a girlfriend. I told my wife the first day we met thatI am a hunter and I respect her desicion not to hunt as she should respect my decision to hunt. I am also a musician and she also respects that as well. Even if it meens me being on the road 4 nights a week. Girlfriends come and go, hunting will always be a part of your life. You need tofind to a medium with her if you truely care for this girlfriend. She needs to respect your decision to be a hunter. But you need to respect something that she does that you dont agree with. Maybe try to get her into the sport slowly and see what really happens out there. If she doesnt like it, then she doesnt have to do it. But if you dont do what you enjoy doing, youll go crazy. I know.
My wife lets me hunt when I want to hunt. She knows its my time to get away from my hectic life. Youll understand what a hectic life is when you are where I am in my life. Youre young yet. Dont let agirlfriend come between your passion for her and the love you have for hunting. But heres the order of what I put first.
Father
Husband
Hunter
Musician

Im a father to my children. I love them, teach them, care for them and play with them and enjoy taking my 7 year old hunting with me. Being a father is more improtant to me than hunting. But If I had only a girlfriend I woudl put my love for hunting above all else. She needs to understand that. if you guys are serious, and care alot about eachother,work it out. Find some common ground. If she cant respect your decision, then you know what you have to do. And if youve been together for a long time, it will hurt both of you because of her greed.
