So until recently I've been the most bp thing you can imagine. I just stumbled onto this subreddit very recently, and I'm trying to change myself as much as possible.

So context:

I go to a big state school where all the attractive women are in sororities, and don't even look at a guy who isn't in a frat.

I met a sorority girl, we were basically trying to get in to the same organization at our school.

Context for the conversation is that I asked her if she got in the organization or not.

There were a couple of texts about how our interviews went.

Conversation below:

Her: Got my e-mail, didn't get in. :(
Me: Me neither, just got the e-mail too. Regardless, what's your week look like?
Her: I'm sorry! I'm not really upset though, it wasn't right for me. I have sorority nonsense all the time haha
Me: I'm not too bothered either, take a break from your sorority nonsense and join me for coffee, day 5 pm location.
(3 hours later)
Her: That's exactly when I have my sorority nonsense haha, 12 - 6.
(12 hours later)
Me: I would sneak out if I were you. I'm going to be there anyway, so come by.
Her: Its a really important ceremony! But I'll see what I can do

I recognized some good stuff I did: - Wasn't bothered when she said she is busy, told her I'm going to be there anyway. - "I would sneak out if I were you", trying to imply I have high value.

I need help recognizing what I did wrong, I feel like I directly jumped in without any real rapport.

Should I proceed with her or forget her and try for someone else? Note that it's difficult for me to get girls who are attractive if they're in a sorority.
