Has this ever happened to your frame? This season is my first time ever using a trainer and I am somewhat concerned about my bike.

...the stresses induced into the rear end of a frame strapped to a trainer are quite a bit higher than normal use. This is due to the frame being constrained and not allowed to move around in a normal manor.

My guess is that if the frame is fairly stout, you should be ok. Also, out of saddle efforts, like interval training, will increase the stress significantly over just spinning to keep the legs limber.

Good luck.

I had the same worry, so like a lot of people, I use an old beater in my trainer. It's a retired road bike I've had for nearly 20 years--wasn't worth selling, so I put cheap tires on it and it lives in the trainer all winter.
FWIW, it's been used for four or five years (after 10-12 years of road use) and is still fine, so the worry may not be justified. If you check places like the Salvation Army, though, you can probably pick up a junk 10-speed (Varsity, Free Spirit, whatever) for ~$25. It doesn't have to work very well, and it doesn't matter how heavy it is.

Apart from not using your good tires on the trainer is to use a cheap skewer on the back wheel. Most trainers clamp on to the rear skewer, and it can be hell on a nice set - mine chewed up the plastic bits on a very nice Ultegra skewer. Soooo.....go diving in the parts bin and grab an old rear skewer for use on the trainer.
