Here's a female point of view. Although I grew up hunting and fishing I don't particularly like camping without some form of running water.Long hair gets itchy when you don't wash it.But back to the point.I myself love time with my BF (of 6yrs). When guys go off and do "guy" things we feel left out and a little sorry for ourselves. Just being honest. But the little things always help me bend and be more open minded about his wants too. Always offer to take her and the kids .If your sincere if your not she'll know. Hunting, fishing , hiking ect... make it fun but don't push them into doing it. I find more help around the house gets the BF more free time.I don't feel so swamped with housework plus kids plus a job that I feel he is having all the fun. So here's the equation: More help + more luv +family time= more understanding and free time.
Up here fishing and hunting comes in seasons not year round so that makes it easier too.(Also that I hunt and fish more than he does. I HAVE to it's a part of who I am.)
But I see the wifes point too .It wasn't hunting or fishing in my case but I definatly wanted more "us time" and it took a major step back on both our parts to see what was really important. I needed more recognition and he needed some space. We were just pushing each other too hard without deserving it.Show this to your wife maybe it will help.
