Hey guys I am a freshman in college still relatively new to the pua community. I understand how different college game is from standard night game and have been trying to modify my game to suit this new environment over these past few weeks. I met this one girl who i am interested in and had a perfect opportunity to f-close her but I did not succeed...here is the whole story
So I was going out with some friends last friday night and one of my dorm-mates brought along a couple girls who I had never met before. One of these girls (the hottest in the group) turned out to be a hb8 so i immediately set my sights on her. I flirted with her (lots of teasing+kino) on the way to this apartment party we were going to and was getting a lot of ioi's, so i was feeling pretty good about the situation. Nothing really significant happened at the party, to be honest I didn't really talk to her too much as it wasn't much of a hookup environment and i wanted to meet new people. When i was ready to leave i suggested that our group went back to my suite where we have a nice tv and sound system and watch a movie. So we all go back, i set up the movie sit next to this girl on the couch, end up cuddling with her and basically having her head in my lap haha. I did not think it would be a good idea to try to kiss her or invite her back to my room with all of her and my friends watching us so i just got her number after it was over.
I decide that i would like to set the goal of FWB with this girl and set out on a mission to do so. I texted her three days later (monday) just so she has my number, send a few flirty messages (mostly C&F) with positive responses and then leave her hanging. She texts me a couple days later, i do basically the same thing as when i first text her. The next day (friday) i call her and tell her to come grab dinner with me (school cafeteria), an invitation she readily accepts. We have a good time talking and stuff and i'm doing a pretty good job teasing her and being cf, when she asks me what i'm doing this weekend i tell her about this frat party i'm going to and tell her she can tag along with my friends if she wants, which she seems to want to do.
That night she texts me and says "her group got split up" and asks if she can go with me to the party. I tell her sure, things seem to go well at the party but i am shocked when i tell her she should come dance with me and she's like "let me finish my drink first" and then conveniently gets another drink when I'm talking to other people. I go do my own thing for a while then meet back up with her and the group, tease her some about how she's apparently "too cool to dance with me" and she's like "no I'm not blah blah" so i ask her again and she agrees. We go down to the dance floor (isolated her from the group

) and have a great time, she seems to be getting pretty aroused. After a couple songs she realizes she left her wallet upstairs by the pong table where we were before so i go back up there with her to find that we're pretty much alone. Somehow she ends up in my arms so i go for the kiss and we make out for the next hour or so. My original plan was to invite her "back for a movie" (attempt to f-close) around 1 but at this point it was almost 3 so i just walked her back to her dorm. She invites me into the lobby where we make out some more for a few minutes, but then she doesn't invite me back to her room (i wasn't sure if it was really my place to suggest that) so i head home.
The next night (last night) i had planned on going for other girls but she texts me and asks where i'm going, i tell her the name of the frat and she doesn't respond but when i get there sure enough she's there as well and basically waiting for me. So i figure i may as well try to f-close with her tonight. We stay at the party for a few hours, dance and make out some, we both get pretty drunk, and then around 1 i invite her back to my suite for a movie. She says sure so i text my suite mates that are there and ask them if they could vacate it for me, to which they agree. So we get back to my suite and two of my friends are there and they're just like "oh hey chris whats up we're just about to go to (name of late night restaurant) to get some food" So they head out and it is just me and her in the living area of our suite. I select a movie but someone screwed up our sound system and i was too drunk to figure out how to fix it so i start making out with her and attempting to get her really aroused on the couch. After maybe 10 minutes i take her hand and lead her back to my room and lay down on my bed with her. We continue making out for a while, i close the door and she doesn't seem to object so at this point I'm thinking "awesome, I'm getting some tonight" After a while i take off her shirt with no problem and continue doing everything i possibly can (with my given state of mind) to get her as turned on as possible (it seemed to be really working) , she doesn't take things further so i go to undo her bra and she just says "stop", i'm a little surprised so i just say "i'm sorry" (probably an afc move). We continue kissing for a couple minutes but the sexual momentum i built up seems to be slowing down and eventually she just rolls over and goes to bed... ...

She spends the night in bed with me and goes home this morning. The shirt she was wearing got messed up so i let her borrow one of mine (incentive to definitely see her again).
I would still like to have sex with this girl (but not exclusively) so it would be great if you all could tell me what i did wrong and where i should go from here...all feedback is welcome.
Also, i forgot to add that at the party last night i had a couple opportunities to # close with some hbs but did not because she ended up standing next to me before i got the chance. Should i still have # closed with the other girls or perhaps more?
