Then you went wrong.....
You should have said
Me: You're probably right, let's find out, I'm coming over in 5 minutes
She would have said two things
1)Ok
2)Make it 10
If she said ok, you were getting nothing, don't go
If she said make it 10, it means she wants to get ready, make sure she looks good, meaning you would get some
In either case, you go over, without texting anything else, and you never text back quick. You wait a few minutes to text back. You never text immediately back. You must be a freshmen too, since you live next to one. You'll pick up swagger eventually, hopefully. Now, back to 1 and 2. She says 1, you go over anyways, and feel it out. You start studying, try flirting. Nothing happens, either rape her, or fuck it, you just study and plant your seed, study another night, make plans to hang out with her again. Or 2, she wants 10 minutes. That means she is getting ready, looking nice, putting on makeup, making sure her roommate isn't around, etc. You will either get some, or fuck up so hard you won't get any, but all being your own fault.
As of now though, you fucked up the texting, which is so dumb, that you just lost any chance with her. Even when she's drunk, she doesn't seem that big of a whore, so you won't get any. Next time a girl texts you, and wants to study....STUDY, and don't send these fucked up texts. Those are texts you send to either a girl you already know, a girl that is such a big slut you know she will eat that shit up. Oh, and since you live next to her, good luck with life this year.
