I guess I am the wife, new to ice fishing 2 years ago. I started going with my fiance. I loved to fish but never went icefishing. He got me hooked, and we love to go out together and fish. Last year we even spilt a new shanty, this year we are getting an auger. I even bought a vexilar! Talk about dedication!
Thing is, and I dont mean to sound overly agressive, but did you ever think your wife doesnt want to go with you so she can have girl time?
Being with your s/o is great, but you dont always have to be glued hip to hip. There is sometimes when I dont want to go only becuase it is going to be a "guy" weekend, and I hate to say it, but sometimes you guys are overly agressive with hunting/fishing.
And you may find a new fishing buddy that you like to "hang" with more than the guys.
