I say hit it and forget it!
Seriously, if this girl is has enough of a problem with hunting and hunters that she doesn't want to talk to you anymore, then she did you a favor. I'd tell her that's fine and move on. At least she was honest and forthright about her feelings on the matter. A lot of women would have kept their mouths shut and tolerated it until they got their hooks in deep (as in, married), then sprung it on you that you weren't gonna hunt anymore.
Plenty of other women our there that won't get between you and your lifestyle... in fact, you might just find one that likes hunting as much as you do.
