Cost is all relative to your situation. When I got my Carbon, 105-equipped Cannondale a few years back, the compromise was my wife could get a "free" ex-show dog. The dog came with health bills and ate like a horse. We probably "invested" $15k in his health and maintenance until his death. That was 10x the cost of the bike.
The frame will hold up. Enjoy your ride. You only live once.
