when i try to a get a jump off it still wont crank and i tested the battery at oreillys . ....
Although it would seem to not be the battery, I'd always want to make certain of that before moving on to anything else. Do you have a multimeter? If not, I'd urge you to buy one - inexpensive and indispensable. With a multimeter, you can do the simple voltage testing, before and during the cranking, which will confirm the battery one way or the other.

If the battery checks out ok on the multimeter, post back in order to do more testing to isolate the problem. But I'd never do anything else until seeing good voltage at the battery with my own eyes.

Batteries are more efficient and function better in warm weather, so yes it's likely that problems will show up in colder weather first. Commercial testers don't find every battery issue, so they can't be relied on 100%. I'm not saying that your battery is the current problem, only that it needs to be proven good for certain, before moving on to anything else.

Over the years, I've seen so many people wasting incredible amounts of time chasing their tail on starting issues, when a bad battery was the problem right from the get go. And all of that could have been avoided with a simple voltage test. If you see 12.4-12.5 volts on the meter before trying to start, and it doesn't drop below 10V when you turn the key to start, then the battery would be confirmed good. And then you move on to further diagnosis.
