I think I got rejected because I was feeling cold

I am refering to literally feeling cold and not like acting "cold" I went on a first date with a girl and it was going very well but then I was rejected when I asked if she is interested to go out again. There could be lots of reasons but I feel like the reason was that I looked a wet puppy because I was not expecting the weather to be that cold and we were sitting outdoor So I started to cross my arms Getting body chills Putting my hands under my thighs But she didn't comment at all What if that was the reason? Idk
