((Hugs)) It feels stupid to be jealous of such things but I am one who will be so you are not alone.
I think finding a training program may give you the push or maybe you just aren't a climber. I find a lot of my frustration mountain biking because I am not a good climber, then I realize I can descend but others walk because they are scared. Find your niche and you will feel better.
About your husband, we share finances so I would be livid if such a frame showed up. I really think you shouldn't bottle that frustration but I am guessing you have or will discuss it with your husband.
And I admit I was pretty dang happy when I was able to get a mountain bike slightly better than DH's because my roadie component group is not as good. Our frames are comparable but I wanted a triple and got 105 he has Dura Ace. My mountain bike has the same gruppo but is lighter and has carbon seat stays, therefore DH declared it "better". Trivial but I sure was happy.
