As someone who has had multiple wives..
tell 'em right up front.. "I _____ (hunt, fish, shoot...whatever)...and that ain't gonna change".
One of two things will happen. She will pout, whine and skulk off...well, let her keep right on going. If she says "that's OK", make it REAL clear right up front what the ground rules are.
My wife bought me 4 Dillon quick-change units for Christmas, and has worked overtime or cashed in vacation multiple times to buy me guns. I told her about a Bushmaster Varminter that I saw at the local dealer...she was upset that I DIDN'T put it on lay-away. Of course, I had to do the right thing and go back to put it on lay-away.
My wife is the greatest thing that ever could have happened to me, but I went thru a painful and extremely expensive learning curve. I can tell you one thing for sure, if they do the pity-party thing up front, it only gets worse, and there's plenty more out there. One of them will be good, but you gotta do a lot of looking.
It's not about right or wrong, it's about compatability. If you're not compatable, you'll split sooner or later. Sooner is easier, cheaper, and far less painful. HTH
