Think I've solved your problem.
Not that any of this applies to you, but let me rave on a bit
One of my pet peeves is when I see a couple with bikes, and the guy has a fancier bike than the woman. They usually have some logic about "she won't use it as much or as hard". So the heavy bike with bad shifting goes to the smallest, least fascinated- by- the- gearing type rider. No wonder they don't ride together. No wonder she doesn't ride as much.
Woman can get years of service from really light gear that a guy would trash. Even in my quiver of bikes, all the XO XTR, carbon fiber stuff goes on Mrs. Newfy's bikes. I get by with XT X9, 32 spoke type things.
So, sell that Liquid (not that liquid is how I'd describe that asset). Then go sell the lightest bike Mr. Trek has. If that doesn't do it, start on the motorcycles.
Then go buy a proper, featherweight bike.
