So in a nutshell I asked a girl out via text (I followed advice on this forum so I did not "ask her" so to speak").
She is on my course but we have different classes. We see each other often at university.
She completely ignored my invitation for lunch.

The question is how do I behave around her now?

I will completely ignore her now and have nothing to do with her but I dont want to come across as bitter or seem hurt (because I am not hurt). And I do not want to give her any satisfaction what so ever.

Lets say she says hello to me or strikes a conversation with me, what do I do?

Yeah, you're obviously unphased by the whole thing. Totally not hurt.
Anyway, yeah, just be normal. Dragula laid it out as it is.

Her dad let her know he's no longer paying for rent so she needs to get a job and self sustain her ass.

Her roommate borrowed a dress and fucked it up by spilling wine on it.

Her ex showed up at her apartment threatening to kill himself if she won't take him back.

She was very hurt by the last guy she opened up to and is emotionally unavailable.

She finds you incompatible.

Point of this post is that there can be a million different external factors affecting her decision. Don't waste time and effort being mad at yourself because you didn't "close".
Some things you can control, others you can't. There's no such thing as 100% success rate.

Let me put this into perspective for you.

Let's pretend you sell cars, okay?

You have a customer who comes on the lot one day and says they are looking at a car.

They go for a test drive, say they like it and they are interested, you give them a price, they say okay, let me go home and get my check book.

You get the car all cleaned up for the customer to come pick it up, get the paperwork ready to go, and the guy never comes back.

You call him the next day, he doesn't answer.

You try calling him again the day after, he sends you to voicemail.

You call him one more time over the weekend and still, no answer.

He blew you off. It's safe to say that he was probably just "stroking" you or something happened when he left. Maybe he bought another car from somewhere else? Maybe his wife put an axe on the deal?

You don't know... and it doesn't matter. Because the lead is now dead. You'll take more customers and you'll sell more cars. You don't treat is as a big deal.

Now, 6 months go by and you get a phone call. It's the dickhead who blew you off before. He was driving by your dealership and saw a car on the lot. He wants a price on it.

Are you gonna get all pissed off because he hurt your feelings blowing you off and tell him to go eat a dick or are you gonna put personal shit aside, think business, and close the fucking deal this time?

There's no right or wrong answer to be honest. It's just a matter of which guy you're going to be.

I run my dating life like a business. Hopefully that clarifies things.

If you see her at the university every day or every other day, why the hell in the world did you invite her for lunch via text? In a uni environment, face-to-face, you simply say...

YOU: "Hi there."
HER: "Hi."
YOU: "Come. Quick. Let's go."
HER: "Where?"
YOU: "It's going to be fun. Let's go."

Disclaimer: I only use this opener and instadate invite on girls whom I have caught covertly looking at my crotch. That means, calibrate.

And who the fuck gave you advice to invite the girl via text when you could have done it face-to-face, hmm? Have balls to invite girls face-to-face especially when you get to see them every day. Jesus Fucking Christ!

Haha would like to see this crotch game and girls rubbing their tits in your face in action. Even then, it could be one Of those data-free placebo things like speed seduction patterns and never being able to find out
