Hey Prodigyy, interesting post dude

I have a thing for asians too (I want to land myself a hot asian someday it's a big fantasy of mine, anime does that to you haha)
Anyway...I have got some plausible answers for you as to why you got rejected man.
I'm going to jump right to it. In terms of attracting here you did a push and pull on her so that you seemed interested but not too interested as to that you wouldnt seem too needy like a puppy in order to get her attention and later get with her, like, you would get with her but on you're terms and when you're ready. Next, you got enough attraction and complience from her so that you were able to make out with her and feel her breasts and ass (nicely done). The part where you fucked I can give you a good answer. When you moved her to the couch and you wanted to touch her pussy, she rejected you, why? You did not build up enough attraction and you didn't sexually escalate sooner. That is key man!
You were lucky to get away with feeling her up! How attracted and interested was she in you when you two where conversing? Was she touching you're hand or any parts of you whilst in her company (Kino)? The main thing is that if you don't get enough physical compliance or enough IOI's from a girl you will probably and most of the time at the end, fail. Plain and simple. You moved WAY too fast onto the couch in my view you gotta work on that. She didn't want to cuddle or kiss anymore because she had lost interest or wasn't attracted anymore, or maybe she was also disappointed? Finally, never, never EVER EVER, come off as needy to a girl. Never. You must make the girl chase after you and gain your affection, if you can do that then that will get you the attraction you want. You came off as pretty needy at the end when you put you're name as "Sexyy ass dudeee" in her phone, that coming off as needy, pushy, sexual, egotistic and just...lame. You also texted yourself from her phone?? Oh my golly

A piece of advice never text yourself from her phone, you didnt even give her a choice in the matter. What you should have done was, when you put her digits in her phone, you should have sent her a text message like after 2 minutes of leaving her saying "Tonight was fun! By the way, who do you think would win in a fight, a Smirf or a drunk kitten?" I know thats sounds silly but that eases some tention on any impending situation and plus it shows you have a funny playful side of yourself, also, it will also remind her of the good time spent with her and she'll get the feeling that she felt from that night when she reads that silly message. If you texted or called her after a couple of days it would have been a little awkward and the attraction would have gone away a little. If she answers the last part first you did good. If you just sent her a message just plain and boring and needy then she may distance herself from you and that may become awkward, we dont want that.
Hope that helps man!
