Is she shy or not interested? She never had a boyfriend?

I'm 29, investment banker, ivy league background, she is 20 in undergard school.

when i first met her she was super shy, although she is a social butterfly. She told her aunt, who married my uncle, that she thought i was super cute and loved my personality. Eventually she opened up and gave me her number. We chatted, flirted, hung out and she enjoyed my personality.

we did this for 5 weeks, we would talk everyday, and then she didn't respond to me, i have no clue why, it was a complete 180. I tried to call her to see what's up but no answer, so i texted her and said if she is not interested in me, that is ok and i would move on with time. But that if she gave me a chance i would support her dreams and make her my queen. When i was younger i came off desperate to women, but now i'm a very wealthy guy and personally, i don't mind if i look desperate for a woman. And even the women from my past are looking for an excuse to "hang out" again but i'm over them, but i think they are just upset they missed out. I just want genuine love.

the things is she didn't respond to that either and i know she saw my text since the app said so on my iphone, i can deal with rejection but i rather here it from her rather than her not telling me.

Ask her.

She's probably not interested. Sorry. You would know if she was. I would move on and probably date other people closer to your age - the difference between 20 and 29 is too large especially for someone in undergrad.
