Well, I'm currently in Barcelona for a few weeks, and I have got this girl's number through a language exchange listing site. I went to her town, had some non alcoholic drinks and I just played natural. We ended up going to a relatively excluded beach, and there were some actions. No sex on the beach though.
It was Monday, and before I left her town we talked about meeting up again. She told me she is coming to downtown Barcelona for a party on Friday night, and since I'm gonna be partying that night too, we agreed to meet up after party and just have sex and relax I guess.
However, I made the mistake of texting too much during this period. I was trying several natural non-canned pick up lines, but it didn't work for her (partly because her English isn't all that well). So on Thursday she made an excuse and told me she has to go home with her friend because she doesn't want him to ride the train alone.
I guess I didn't realize that I was chasing too much. So insisted even more (bad choice). I asked again (bad choice) on Friday night at 3am, and she was saying no again (no wonder), and she literally told me that she will text me when she wants to have sex with me.
So I texted her on Saturday morning again, basically joking and flirting about what she said last night. Then she told me that the truth is that she is bored of me, and she she doesn't like easy boys. She told me I text her all the time and it turns her off.
I have never encountered this kind of situation before, a girl literally telling me that I bored her. So with some alcohol still in my system from yesterday, I told her "oh yea, then fuck off".
I know this doesn't look that good to me right now. The problem is she is really hot and my type. And I would definitely put into more efforts if I still have a chance.
So what kind of game should I play right now if I still wanna have a chance with her? Or should I just go try to pickup the countless drunk tourists in Las Ramblas?

Also I'm 18 and she is 21. I'm half Asian and half White and she is White, if that matters.

Sorry man,

You no longer have a chance. You're done with this girl. Forget her and learn from your mistakes.

Texting too much, not being a challenge and being needy got you into this mess ---- and you think maybe doing more of it will get you out of it?

Take lessons learned here and improve for next time: best thing you can do, cause she is out.
