Bare with me, it's gonna be a little bit long.

 

It's happened twice in a week already: girl shows interest, gives number, suggests we'll see each other in the future but the does not respond to texts at all. I simply do not understand.

 

3 days ago I approached this highly attractive girl at a bus stop, we chatted for a bit, I told her I had just moved into this neighborhood and asked if she was from around, she told me she had lived here her whole life and that she'd be happy to show me around some time. I ask for her number, she says "yeah, we're from the same neighborhood, we'll definitely see each other again" and gives it to me.
We then get off the bus, I kiss her on the cheek goodbye and she tells me "I'll see you around then" with a big smile on. I just smile and say "Sure". And we part ways.
I text the next morning and she never replied, waited for a bit, texted her again and still nothing. It kinda bugged me as she was seriously gorgeous and thought we had connected but I simply moved on.

 

Now this morning, this one is the one that left me completely befuddled. After a big party last night, on the subway on my way back home, I see this beautiful chick, maybe not as pretty as the first one, but what a body. She's carrying luggage and still has the airport tags on it.
She sees me, we make eye contact, and we get off the subway I approach her asking where she was from legitimately thinking she was from abroad as a lot of young exchange students come at this time of the year. She smiles and tells me she's from here and that she recently traveled so that's why she still had the airport tags on and engages conversation. I'm going to take a bus back home and she's taking a train, but from the same station. Her train is about an hour from that moment so I chose to stay with her while she waited (she nonchalantly suggested it by asking where I was going and what I was going to do next).
Now at this point we're talking as if we knew each other for ages, laughing, joking around, kino'ing hard. She suggests we go for a coffee while she waits for her train, we sit across from one another. She's asking me all sorts of questions and I do the same. She tells me about her new apartment and even says "you should check it out some time". At this point I am positive there is mutual attraction. I ask for her Facebook, I hand her my phone, she types her name, I add her and tells me she'll accept my friend request later when she's home as she doesn't have an internet connection on her phone.
We start talking about what we do, she tells me she's gonna start working at a clothing store this Saturday and that it's gonna be very intense for her because it's a lot of work hours. I seductively ask "Are you going to have time for me then?", she smiles and says "We'll find time to see each other!".
I say "You know what? Give me your number, I think it's simpler that way", she explains to me she doesn't know it by heart because she recently lost her actual phone and is using an old one with a new SIM card, so with a new number so she simply tells me she's gonna take mine. She hands me her phone so I can type my number, she tells me to ring myself so I have hers, I do, I save her as a contact and just keep chatting to her. Her train eventually arrives, we go to the gate, she says "We'll keep in touch then!", I say "Of course!", kiss her on the cheek good bye and leave.
Later, I get home, get on reddit for a bit, usual stuff. I go and check her Facebook profile and to my giant surprise, the friend request is gone, it doesn't say "Request Pending" anymore, it just says "Add Friend". I get super confused, I even think I maybe didn't actually add her though I was pretty sure I did, so I add her again. A few minutes go by, I check again, same thing, request gone.
At that point it's clear she cancelled my friend request twice, I do not understand why, I go ahead and text her "You didn't accept my friend request on Facebook? :o", it's been several hours, she has not answered at all.

 

What. the. fuck.

 

Now, I'm an attractive guy, I am confident, I usually pull girls easily. And I'm currently seeing two girls (casual sex). They're beautiful but I'm not necessarily attracted to them.
These two I was really attracted to, and they're the first ones I approached out of nowhere on the street. I just recently started doing so, slowly improving my day game as I'm new to it, it's usually Tinder girls, or girls I have common friends with or even girls from college.
I believe I know how to talk to women, their reactions to my approaches even back up that claim. But I don't understand. Why even bother staying with me that long, showing CLEAR signs of interest, suggesting we'll see each other again, and then simply ignoring the shit out of me.

 

I am not used to this feeling of confusion at ALL and it's driving me a little nuts (nothing serious), I keep telling myself I do not get it.

 

Any insight?
