Does there father give any reasoning as to 'why' he doesn't want them hunting with your boyfriend? Not knowing the story behind why things are the way they are now, hard to say why there father is being the way he is. It sounds totally wrong to me and I feel for the kids with 'Dad' putting them in this position to choose. Like timbercruiser said above, "Sounds like the father can't accept the fact that things have changed in the family's lives." About sums it up IMO.

Nothing wrong, what so ever, with hunting with different 'groups/people', like you said, can always learn different things from different people.

Hopefully, you all can work something out.
