No, this isn't about being unable to approach someone, for what the title suggests. It's instead me wondering if nervousness while near a certain someone can mean you are attracted, as you're worrying about what'll happen, or how you look etc. I ask this because the past few days I have been pretty nervous, even when nowhere near, just from idle thoughts; but now the majority of it has suddenly disappeared. It made me wonder, if it's linked., I am by no means very knowledgeable on such things, just wishing to know out of curiosity.
Thanks to any replies in advance.
