I had the same kinda thing happen to me in Uni. I did not escalate faster and a good friend of mine (then), fucked her, she thought I was gay after I did not respond to her IOI's, apparently.
Look, realize everything that comes out of a womans mouth is a test. Everything, even as she is spitting out a load, mauahha.
Pick up David DeAngelo's Double your Dating, will really give you an eye opener into what is going on in her mind and how you should act...Besides the game, that book blew my mind and opened me up to women.
Anyway: Quick rundown...IT IS NOT TOO LATE to get the ball going, the great thing about college is, its full of second chances and yall are around each other by circumstance instead of at random....That is good news. Don't think next Friday is it. Could be a bunch of reasons why she avoids being with you alone, I choose to believe that she is so crazy about you she might just jump your bones and get freaky with you if she does so, she avoids it....Might be a good mindset to take...
Romance is not everything, you have to show here IOI's too, and not everything needs to be romantic...Pick on her...be playful, again, show interest, hold out your hand and see if she will take it, ect...I am sure you are familiar with push pull here.
Get her interest, step away, step it forward, step away, do this until she is crazy about you, TBH it sounds like she is open minded about it and just needs a show from you.
Also, telling her about a ONS you had might not have been the best thing ever, but if your reputation is that of a player you might just be fine, just don't mention anything like that again...She probably figures your DTF.
From here I will let a more experienced PUA take the reigns I am still AFC.
