Ummm ok so what was the IOI’s you mentioned. Sounds to me like she was just being friendly. Its not looking right at you and smiling thats a IOI. Its quick glancing looks. Smiling just means she is approachable.
You mention she is cold all the time. Maybe moving closer to you is a subconscious attempt to move towards warmth. Your body heat drew her closer.
This is her sensing your attraction and attempting to put you in the friends box. She is indicating she is looking elsewhere.
Was it a friendly touch or a sexual touch ? Women are more touchy then men. Its a natural instinct so it depends on how she touched your face.
She realizes you didnt get the subtle hint earlier and now has to push a bit harder to keep you in the friends box so she gives more obvious hints of her interest in you juat as a friend.
And she slammed the lid on the box.
And you know that hers is opposite yours how ? Body heat is not a indicator of your immune system really.
I am sure she does but as a friend.
Look at this post

All of her behavoir indicated she wanted a friend not a boyfriend.
Sorry if this seems harsh but you need to know your in the friends box.
Mones may be able to influence her if the IOI are there in the friendship but mones just enhance whats already there. They bring it out they dont create it.
