<human>: Throwaway because she uses reddit. 

So I've been with girlfriend, i'll call her Allison for a year now, she's very sweet and kind and beautiful. She comes over to my house a couple times a week, but she always complains about being cold and it kinda worries me. I ask her if I need to turn up the heat but she always says no and that it's fine which confuses me even further. I'm worried she might be sick or something, but she doesn't act sick besides this. Has anyone ever dealt with something like this before? Any advice is appreciated.

Can you summarize the given text in a few sentences?
