Hi guys,first post here. I'm 19 years old,from Argentina (so in advance sorry for any writing mistake) and I've been lurking on seddit for a while now.

Days ago,in a trip with friends, i meet a girl on a night club (let's call her Sophia). She approached me while i was dancing with my friends (the club was really empty),and told me that a friend of hers, wanted to hook up with a friend of mine. I immediately noticed that she was pretty drunk, and i just had some drinks, not drunk at all. She was an 8/10 for me, so the game was on. I responded "I don't know about my friend,but i like you", she laughed while staring/dancing at me. We started to talk,and i find out shes 23 (never been with a girl this "old"). I tried to escalate things with some kino and dancing but a friend of hers wanted to leave (classic situation). I couldn't manage to kiss her but i obtained her number.

The next day, we hanged out in the beach (her friends and mine). She wasn't there most of the time because early on she found another old group of friends,and went there to say hi, so we talked like for an hour in the whole afternoon. I spent most of my time talking to her friends and just general chatting.

When Sophia came back with us, we planned to hang out again that same night. (here in Argentina, there is a thing called "previa" -pre drinks-, where we hang out in somebody house, before going to a club, and get drunk as fuck. Sophia invited us to her apartment. (me and 3 friends). Her group of friends was of 5.

Later that night, 12:00 pm, we went to the apartment, brought some alcohol, and the "previa" started. Everything went amazing, non stop talking, laughs, music, drinking games, everybody was having fun. At 2:00 am (we usually go to the club at 3 - 4 am here), i decided that it was the time to make the move on Sophia. At that time we all were drunk af,so i told her, "help me to make a drink in the kitchen",so we were alone. I don't know what the hell i said there, but i know it was some clever shit for sure. We turned off the lights and started to make up, then our friends appeared, and we moved on to the balcony, keep making out for a while and then it was the time to go to the club. Sophia kinda wanted to go,but i quickly convinced her to stay with me, but most of her friends wanted her to go to the club. So it was me against her friends. Fortunately, a god- sent friend of her, realized that we wanted to fuck the hell out of each other and convinced to let her stay with me. They left and not to later after that, we were in the bed. Sex was amazing,she seemed to enjoy it a lot (big difference between a 18 and a 23 year old girl). We had a little argue in the middle of the session because we started without condom (she was on the pill) and out of nowhere she started to demand me to use a condom. (she was right btw,but dumb fuck teen of me, didn't wanted to use one, so i tried to convince her, lying that i didn't had condoms), after some minutes of arguing, i told her that i may have a condom on my wallet (lol i had 3 of them). She realized that i was lying and seemed a bit pissed off (i don't know if she was joking, because it sounded as a mix of pissed off and horny), but oh well, we continued.

After finishing, we talked and slept till her friends came back from the club. And after that, i left to my apartment.

Here is where all go down road. I thought to myself "nice, i have a girl to fuck during the trip that lives 3 blocks away from my apartment and shes hot af".

Next day, we didn't text each other. BUT, a friend of mine, did text a friend of hers to hang out, and she seens the message and don't respond.

Two days after fucking, i text her "hey, hou are you doing?". Wollah,seens the message and don't respond. Same thing with two of my friends that went to that apartment to hang out and texted the other girls. No fucking signal.

So, what happened ? Did i messed up somewhere in the middle? Was that just a ONS girl ? I felt like used LOL, at least respond the message. All of the girls told us that we were "the coolest guys" that they meet there, and that we were really easy going and funny,and blah blah.
