I am and a woman and am not offended by the idea of wanting someone who's fit, healthy and active. However, I do see your approach to the outdoors as being a little too intense. You say >>So what is the point of getting married if there is nothing you can do together you both enjoy?<< Does this mean that there's nothing else you enjoy other than the outdoors? You don't like theatre and restaurants and dinner with friends? You don't like photography or reading or music? What about nice drives in the country?
Thing is, even if you find a fit and healthy girl of your age, odds are that she'll want more in her life than outdoors and sport. And she'll ALSO want someone to enjoy them with.
Taking it further, you say you want to start a family...and keep climbing and rafting and sporting.....good luck with that! LOL Like it or not, having children will have a negative impact your ability to participate in these activities. Sure, you can keep skiing if the resort has a crèche and, later on, kids ski lessons, but who's going to be with the kids if you and your wife are out climbing and hiking frequently? What about needing to be around on weekends so that you can take your kids to birthday parties and little league? Yes, I too remember saying that our kids were going to fit in around our lives....how delusional we were LOL
And if you're like us and have a disabled child, you will find that it seriously changes all the way you spend your spare time. We're currently trying to figure out the future of our skiing because our son is disabled enough to not be able to ski, but not so disabled that he qualifies for a sit ski. He hates the idea of being left at home with family but complains about being in the lodge for a weekend.
There is also the thought that we don't have to share ALL our hobbies with our partner. Hubby and I love to ski and surf together, but he enjoys his soccer and tennis without me. He doesn't need my presence to make it enjoyable. Frankly, I think having individual hobbies is healthy...I'd hate to spend all our free time in each other's pockets.
What I'm trying to say is that finding someone who can participate in some (not all) of your activities is great. But you need to loosen your criteria somewhat. You're not going to find someone who loves everything you do. And also remember that people and our life situations change. We have children and get age related injuries and we never know what's around the corner.
I'm not in the US, so I had to Google Madison. Apparently it's got a population of 236,000. You're not in a small town! There has to be more women out there if you loosen your criteria a bit. And if not, why don't you move to a bigger place such as Chicago? Join a climbing club there and see who you meet.
Lastly, there's no way I'd even consider a marriage broker.
Never regret anything that has happened in your life. It cannot be changed, forgotten or undone. So, take it as a lesson learned and move on.
