Obviously
@Visionist you're blue pill and lacking some experience. Tell me please, why would your friend try to set you up with a girl, eh? Obviously, because you're single and thirsty, or in other words unsuccessful with women. Your attitude in your original post reflects it. Either we see each other, or no. As if you have other options. Perhaps you do, but not a lot of them.
With this girl, everything is lost, she said we'll see. That means a no. Natural thing of chasing her ass will not do anything. And there is no such thing as in italian culture (or whatever culture) you have to chase them, or she is old fashioned, or whatever. No! World doesn't work like that. Everything in this world is constant with DJ game no matter the culture.
I can bet my two cents that your texting with her was 100% platonic, there was no flirting. There is also good chance that she didn't even sht test you, or if she did you failed, or didn't even see it. So asking her out from platonic phase?? What kind of result did you expect here?
I can't text, that is an excuse you made up for yourself.
I can't talk on the phone, that is also an excuse you made up for yourself.
As if when time comes to meet with her in person, you will be that prince. No it won't be like that. When the time comes, you will be saying I can't meet with girls, I prefer just go straight to sex part and be done with it. Then there is no point in women whatsoever, god gave you right hand, use it.
Texting can be learned by watching youtube and practicing. Talking on the phone also can be learned, again youtube and practicing. When you saying I can't text or talk on the phone, all that means you do not have experience and afraid to try it, your mind just shutting you down. You even coming up with excuse, it's either she meet me or fck it.
But why would she meet you? You are not interesting.
No, texting her more, warming her up, or whatever you call it, will not work. Kissing ass never works. In fact she already has an idea of who you are, you can't change that frame. You see, each text conversation (online dating for example) has four parts to it. Silence, Sht test, platonic, flirting. You treat each part differently, you approach each part differently. You do not ask her out when she is giving you silence, you do not ask her out when she sht testing you, or when you two are having a platonic conversation - sht, what you do for a living, I work at a bar, do you want to go out? We'll see.

That kind of sht has a place to be, if you're an underwear model with build body, and are a 9 to chicks, so that they jump on you, it sometimes will work. But you're not, stop acting like you are.
You treat silence with fun witty one liners that are about you and her, and you don't ask questions, something she don't have to reply to.
You treat sht tests like her investing into you her time, good thing, you just pass the sht test, and don't follow up, ask questions, you let her come back at you.
Platonic conversations are good, and you write something short and flirt to get out of it.
Flirting is when you start making plans, that's when you get her number and give her a call and flirt some more on the phone.
From this phase you make a qualifier question, vague suggestion, find out her schedule, and make plans. Are you an adventurous person? What’s your view on drinks and witty banter? When are you free this week? Let meet this day this time!
You had a conversation which was going nowhere from the start because you had no plan. Start planning your moves.
