I took my wife hunting once , now I have 2 great hunting partners . My wife and my 8 year old daughter. I take my 8 year old more than my wife , she wakes me when the deer show up(great little alarm ). I caught her once digging in a gut pile tring to find the bullet. she got into a fight with a boy at school when he told her girls cant hunt. He now knows better!( she made tough guy cry )
At 5 years old we spent4 hours in a blind togeather. I had to beg her for us to leave.
I put 5 pounds of corn on the ground 30 yds in front of us and gave her a pair of binoculars,she watched squirrels all day.

Take your girlfriend hunting , just dont force it on her!
