I need some girl advice please.?

Theres this girl i meet a little over a week ago at my cousins house. When she first saw me went off into a dead stare into my eyes and so did into her eyes. When she was leaveing she looked back at me while riding off with my cousin on there four wheeler. Then i see her about a week later i dont see her often ive saw her twice. And the second time she saw me i had my shirt off because i was swimming and yes i got a 6 pack. And she looked me up and down 2 twice along with getting lost in my eyes and so did i yet again. And my aunt which is very cool kinda caught me looking at her and she smiled at me asked if i thought she was cute i said yes very cute. Then my aunt said yes she is cute. then i said you can tell her i said that if you want i dont really care. She said she would and the only reason why havent spoken was because of my family being around and its out side of my comfort zone to talk and try and flirt with any girl infront of family. yea call me a wus or wat ever but everyone has there fears. so is this girl interested or not? And was it a bad idea to go on let my aunt tell her i mean i dont think im weird for it im honest about it atleast which is more than i can say for most people i think. And they lve next door to my aunts if my cousin isnt there would it be ok to just walk up there and ask her to go for a walk or hang out and that im from next door at her friends house? And what if her parents answer that door what should i say and i dont know her name or anything so how should i request her presence say is your daughter here that sounds kinda weird and knowing her name isnt that kinda weird? so how should i approach that and what should i say if her parents answer the door? just tell her im from next door and im her friends cousin? please pst what i could say when i go to to her house and ask her to hang out. and should i find out her name b4 i go to her house or no need to get her name before i knock on her door? please comment.
