Okay i personnaly become strangely shy and quite when i am with someone i have a crush on if i have strong feelings i will be very caring and considerate of yours and will try my best to make you happy i will check on you a lot to be sure that you feel good and everything is alright . I think we ENFP can seem very open to people when in fact only 1 or 2 person know our true self i don't know do you feel like you have seen her in a way that people don't know because if yes she probably really like you i take the risk to open up on my true feelings and my "sad" and sensitive side only to people i love (close friends , lover,family) if she is confortable be vulnerable in front of you i think you have your chance it mean that you created an intimacy and this is what we crave the most ( i mean personnaly) . So is she open extrovert but still a bit shy around you ? Like she wabt you to see her at her best because if i like a guy i will try to not embarass myself ( wich sadly often leads to me embarassing myself :( ) anyway if she try her best to keep her composure because she wants you to appreciate her you win i don't know if this is how it work for other enfp but at least this work like this for me and one of my enfp best friend is like that to i observed Sorry for the long text i hope i helped you Oh i forget do not be scared to do the first steps because personnaly i hate to do it and i am so scared i had a crush for 4 years and never tald him because i was to scared of rejection to humiliate myself and very shy i had strong difficulty to articulate myself in front of him which is not how i am usually Anyway this time i am really finish Ps : i am from europe so sorry for my horrible grammar
