So last night was my senior prom and it was actually one of the most nights of my life despite not hooking up with anyone. So I went to prom with my friends friend, a 6. I didn't know her previous to prom and met her at pictures. She seemed nice and is actually pretty shy but I did not feel attracted to her. I still tried to make sure she was comfortable, talked to her, and just tried to be a nice guy in general to make sure she was having a good time. So after pictures we get to the dance where I meet up with my friends and the rest of the senior class. All of my friends are going with their dates as friends which is good for me. One of them, a 9.5 in my opinion, is my target for the night. I do not know her well but we have texted/snapchatted (a good way of keeping in contact with girls by the way) in the past so she knew who I was. One of my main problems is becoming too obsessive and clingy about girls I like, but I have been working on this and just tried focusing on having a great time. By the way, my date disappeared after we came in and I had no idea where she went (there are almost 700 kids in my grade). So this whole night I'm just having a great time, dancing with everyone, being my goofy self, and also dancing near/with the 9.5. One of my friends actually did something really funny: while I was dancing, he angled me towards the 9.5 and gave me a nudge towards her which was pretty cool of him to do. So after 4 hours of dancing, a failed crowd surfing attempt (it worked at junior prom!), me, my friend who we will call "The Host," the 9.5 (the 9.5 was the hosts date...they are just friends), and my friend who we will call "The Potential Threat #1" all took a ride back to The Hosts house to prepare for the after party. So we are all hanging out getting ready and I'm one of the funniest people in my friend group so I'm doing my usual antics and everyone is laughing and having fun. I call my mom cause I want to get a change of clothes, sleeping bag, and my car so I can sleepover. So I tell everyone that I'm gonna wait outside for my mom. Everyone follows me upstairs and when we get to the front door, the 9.5 comes outside with me and the two guys back off. I now perceive this as them giving me a chance and I can't believe I didn't realize it. So I sit down on the stone steps and she sits right next to me. "Hey we haven't really met yet," she says. "Hi, I'm Samthemastodon, nice to meet you!" (She knows my name already). She laughs and says "Hey I'm 9.5, nice to meet you." So we sit there and we are talking. I am pretty shocked because a girl has never done anything like this to me but I am acting as my usual self and trying to not be awkward. Magically, I am actually not freezing up or doing anything awkward as I have done in the past, I am talking to her, smiling, and looking her in the eyes. By the way, what is the trick to keeping eye contact and fighting the urge to look down? It's so hard haha. Before I get a chance to escalate things, a car pulls into the driveway. I thought it was my mom but it is 5 more of my friends arriving. She says "Hey I'm gonna go inside now, do you want me to wait with you more?" I say no its fine I will meet up with you later. I regret this but I also want to walk to the end of the driveway (its a long ass driveway) so my mom doesn't get a chance to see or hear the party. As I walk up the driveway a bus pulls up and 50 kids get out and go down the driveway to the house. I see a few more of my friends pull up, including "The Best Friend." Now he and 9.5 used to be dating/hooking up but he doesn't like her anymore and already has a girlfriend. But 9.5 still has feelings for him apparently. So I before he pulls in the driveway I ask him to talk to me later cause I want some help with 9.5. He says ok and goes in. Fast forward like 20 min and I am back with all my stuff and there is about 60 kids here. It's party time. I decide to leave on my all black tux because I love it and everyone has complimented me on it. So I we are all just having fun and I am making no real effort on trying to get with any other girls other than 9.5 so I am making sure to be in group she's with. She's not really paying attention to me anymore and is focusing on The Best Friend. Me and the Best Fried leave for a bit and come back. She in the process of going around and kissing everyone and she kisses everyone but us. She says something like "hey you guys missed it." I say, "well, we are right here." She then walks up to me and makes out with me for about 5 seconds, giving me my first kiss with a girl although it was not as great or long as I expected it. Then she kisses The Best Friend and I get suspicious because of the way she's been acting to him. Ok and now the single biggest regret of the night, and the biggest mistake I have made. She is sitting in a chair and says something like "does anyone want to cuddle with me?" I freeze up and my mind is telling me to go for it but for some reason I can't get the words out and then one of her friends (girl) sits with her. Here's where things take a turn for the worse. She is now making out with The Best Friend and I am very angry, not just because of jealously but also because of their past. Upset, I leave the area and go hang out with everyone else and I start trying to forget about this and have a good time. I go inside and randomly start grinding with some 10 who I didn't know for a few. I wasn't that interested in her cause she seemed crazy and eventually left and socialized with other people. Best friend walks away after like 5 min clearly upset about something. Now both of them are just moping around separately talking to their friends about something. I eventually confront him and he says he is sorry and she just popped up in front of him and went in for the kiss and he couldn't do anything cause he wasn't in a very good state of mind and body haha. I know he is telling the truth and say ok fine but please help me. He is still upset he has done this and wants to leave cause many people are very upset at him. I protest and say its fine but he leaves. I walk around for a bit and go to the driveway where there are no people and he is there talking to her trying to resolve the situation. He leaves and she walks away clearly upset. I say "Hey 9.5, are you ok?" She mumbles something and quickly walks away, still upset. Not wanting to be clingy, I keep my distance and stay away. Now later the evening I see her talking and I think flirting with A Potential Threat #2. I have never seem this guy before and I kind of give up on this whole thing. Te rest of the night I just have fun with my friends. A bunch of us sleep over, including her. The next morning when I leave I give her a hug and say, "It was nice meeting you, let me know when you are in town again." She says "nice meeting you too, I will definitely let you know and then l leave the house and go home.

TL;DR I try and get with a 9.5, it goes well in the beginning but then fails from my failure to read many important signs and general stupidity.

With that being said, I had a blast that night but wish it could have been more. Sorry for the wall of text but I hope you guys can see what I did wrong and hopefully critique me on my mistakes so I can succeed in the future. I am still in contact with her and she is coming back to my town in a few weeks. Thanks Seddit!
