Need Advice on a woman (please)

I live next store to this nice big family in Indiana. Very nice small town in corn country. They have 2 sons which are moved out and married and 3 girls which 2 live at home going to college, Liz 26 and Carrie 19. Carrie is with her life long soul mate daily. Liz has a boyfriend of 9 years that lives in UK and they see each other twice a year. (sounds little weird, but 9 years man means something). About 2 years ago, I noticed Liz in a different light and I think she knew that I knew I was checking her out. Something just changed out of nowhere, in that split second. She's a showstopper for sure and well educated, formal and polite but sarcastic which I'm very sarcastic and been like that my whole life. Prior to that time, I never 'noticed' her, just some college girl that lives next store. Her Mom and Dad are great folks and her mom who is in her 60's admires me A lot, like I can do no wrong.
Back to Liz, anytime we are around each other I feel a sort of connecting non-verbal vibe. We avoid each other like little kids. A group of 12 of us (family and friends) were watching fireworks, small town deal. She got home from school and came out dressed like a model. No other dudes were there to impress but man alive, she was incredible. We've hardly spoken to each other yet all other family and friends I talk too and back and forth, good times. I can say countless stories of looking at each, catch each looking but nothing verbal is said. I am 'friends' on instagram with her Dad, Mom, sister and brothers., but not her. My instagram profile pic is me sitting on top of a mountain (love backcountry hiking and camping), hers changed to her standing on top of mountain and it says "wander often" 'wonder always' - maybe it's some subliminal thing, heck I don't know. The staring game we do is off the charts. Overall, she's a 16/10 on all levels; mentally, verbally, physically.

Enough of the all-over-the-place narrative, does she like me or am I going AWAL and thinking way too deep on this?
