And also to let you know that my H loves hiking. I'm talking really looong hikes of 15 miles or more. Me...I can "hike" for 2 or 3 miles before I start to become crabby with it. I will go with him (or did before we had little kids to contend with) but I will never do it all the time, nor will I ever share a fraction of the enthusiasm that he does.
What we DID do, however, was to find a way that we can both enjoy the outdoors together. We bought these cheap bikes (I know you will be horrified at this, lol) and we go for bike rides. He gets his exercise, I get to be outside, we spend time together and neither of us is let down at all. Oh and we bought a bike trailer and can take the kids with us, too, although that sortof ruins the Mom&Dad quality time thing goin on.
My point is that you might have to find a way to incorporate her into your life without having an expectation that she will love it or begin to want it on her own. In fact, it might come off sounding arrogant to her..."If you only knew more about it, you would love it" Well maybe she would and maybe she wouldn't.
Picture if she had a hobby, say scrapbooking, that she wanted you to participate in. You REALLY did not have much interest in this but you DO have an interest in your wife so you agree to go to a scrapbook party and help out with making some pages of your family next time she does it. Is this sending a chill up your spine? (it is mine, incidentally!)
So maybe you should have several plans in mind for how to go about finding mutual recreation together. Not you bringing her over to your hobbies or vice versa, but the both of you doing something entirely different that works for each of you.
P.S. I do NOT understand how a person can ride 30 miles on a mountain trail. Last summer (over the 4th of July weekend) I surprised H with a trip to a lodge and we took our bikes and rode 5 miles on the trail. Honestly I thought I would die several times. I know that H probably felt like he does when riding with D4 with her training wheels but we had a blast!!! He still talks about this trip, in fact. So.............it wasn't hiking (which is what we have always done when we go to this lodge) but we still managed to find something that appealed to us both.
Food for thought! Glad you enjoyed your ride last night...sounded beautiful.
