Hi guys! I'm a newbie here, hope to learn as much as I can from this community!

Here is my story of last weekend:
Friday night, my buddy and I invited 2 (already a bit drunk) girls into my house. We had some good time! I served them with drinks, we had really good conversation, we neg then from time to time, laughed a lot, some real fun time.
Through out the process they were very responsive. From the target we had some really good sexualy open jokes. she kept teasing us with sex remarks - for example she saw a tissue and said - "I see someone is getting bussy around here". Offcurse we had some good answer for all of these tests that really made them laugh.
After some time the target just went into my bed and fell a sleep So we shut the light off and joined her. 4 people in 1 bed. I joined by her side and my buddy joined the other girl. They kept talking for a bit and then they made up until they also fell a sleep. A funny side of the story, the target started snorring! Lol! We just laughed about it and she woke up! We told her its funny that she snores.. So she responded "Like I care״ Then I told her that she woke me up and she responded "Don't worry it's the last time we are going to sleep together" not far after she asked me to sleep closer to her.. So I did.. I held her in my arms and we fell a sleep again. Next morning I gave them a lift back home. First I dropped my buddy's girl in her house and then we went to the targets's place. Before she left my car she told us "What are u guys saying about watching the big brother and a sushi in my place? And I answerd (like a dumbass) "Nah, I dont watch the big brother" (really, I thought she was talking about now rather then evening). Then she left. More than that I didn't even took her number! It was like the shitiest way of saying goodbye to her.
As I drove back home, My buddy enlighted me of what just happend, It was really stupid I must say. When I woke up after a good sleep my buddy and I went to grab some food... I told him that I shall ask her number through facebook. So, we went into facebook. Here is a copy of the conv. Check it out:

Me: whats up, sleeping beauty?
Her: Good. I was sleeping like a queen until 5:30pm!!
Me: Haven't you had enough sleeping at my place already?
Her: No... It was too loud
Me: Yeah! Not to mention that most of it came out of you
Her: Basically you are right... It was an outcome of me being exahusted
Me: It may happend to all of us
Her: As you can imagine, I don't really care about it
Me: Lol
Her: I just arrived from ___'s (Her friend's name)
Me: Cool. So, what have you done there?
Her: We watched the big brother and had sushi. Awsome
Me: As I remember, this morning you were looking for a partner who will join you for the exact same thing
Her: For real?!!? Totally unbelievable...
Me: Probably you were way too high to remember... You even proposed swimming naked together
Her: No wayyyy... So have you decline my offer? Sucker
Me: Nope, not really. We agreed on meeting next weekend on a sushi and naked swim
Her: Have you agreed? Yakkkk disgusting
Me: Yeah, really disgusting. Long story short, I really have to go, write down your number so we could continue our conversation soon
Her: quiettttttt. It's a secret! I have a military phone number
Me: So, the number... Now
Her: Go, bring yourself some popcorn
Me: Nah, I have some ____ (A name of a stupid food), goes well in winter time
Her: If I only knew what that is...
Me: I'll forgive you for that this time
Her: Oh, thank you, really
Me: Anytime

What went sooo wrong that she had to act like that? Disinterest? So why so hursh... In my opinion she really acted like a little girl...
What do you guys think?

I think she was just playing around with you a bit, then you probably came on a little too strong with the 'Now' part.. Maybe if it was in person you'd be able to pull it off, but talking to people through text is difficult to show certain things like tone, pace and facial expression.. All those things help deliver a line perfectly.

I think it was pretty good up until the number part, and had you played along with it a little longer and given a witty response about the military number, you woulda got it.

Is there anything to do about it now? In my own opinion, I think not, but I'd like to hear what you guys have to say about it?

I don't really know before I joined the forum / read anything about PUA, I would've done something like started a conversation again, then been like 'so.. if it's okay with the military, you should give me a call sometime ________'. But that's giving her your number.. I dunno.

Try make that ^ more playful and turn it into a way for you to get hers?

Well,you sounded desperate with the 'Now' instead of whatever you wanted it to sound like. Trust me,it can be salvaged. Just do some normal fun talking for a day or two and then ask for it again.. if she refuses, just tell her that 'Yeah,you should totally play hard to get, I am going out for a bite. When you're ready to give me your number,let me know and then,we can talk like normal human beings.. dork.' Works on most women. Tested.
