Red Pill, I need help... Backstory: I'm a 15 year old male who has recently swallowed the red pill. I'm about 195 pounds, 5'10 which makes me slightly fat, and moderately attractive face-wise. I have worked on losing weight and I dropped 9 pounds over 1 year and plan to continue. I found out about this amazing subreddit about a month of being with my current girlfriend. The past 4 months have been pretty good. I've fingered her and gotten blown before and almost lost my virginity but I got nervous and couldn't get it up. Since then I stopped masturbating. I know my girlfriend is easily able to get another guy but right now I assume she hasn't yet. Our relationship has been good up until the last month where things have been more distanced between us. Recently however I've been working on getting closer to her so that I might have another chance at sex soon.

      The problem: I have a dance at my high school this weekend. One of my friends tipped me off that my girlfriend didn't want me to go so she could be a slut the whole night without me knowing and then go back to our normal relationship as if it never happened. I dont know if this is true but she is the type of person to fool around. The friend that told me is a very good friend that also happens to be a girl and she said she heard it through my girlfriend's best friend. It does help having a friend that I'm not trying to fuck that's really close to a lot of other girls. She's sort of like a wingwoman.             The solution: We'll I don't want to break up with her only to have her not do anything with anyone else at the dance because some of my friends would resent me for it and she still has a bunch of my shit I want back (I'm stupid for giving it to her but I can't change that now). Right now my plan is to prepare to either dump her or get dumped by collecting other girls numbers so that if/when she cheats, I can dump her, call up the next girl and at least hookup with someone else before the night is over. If she tries to find a way to hook up with other guys and still be with me I'm dumping her. If she even says the words open relationship I'm dumping her. If I can't go to said dance, I have a friend willing to spy on her for me if I don't dump her before which I probably will. I can get other girls because there happens to be some attractive unexperienced girls in the grade below me I can date or hook up with. I also don't want to dump her so easily because I do have a good chance of fucking her soon. I don't use the red pill techniques as much as I want to because I didn't start off using them so she would know the difference. I do use them enough to be seen as the dominant power in the relationship however.          I don't know what to do but that is what I currently think. I don't want to go back to being beta ever again thinking I have no chance with any girl and that I should worship her for just dating me. I want to play this out so I can lose my virginity ASAP and have a girlfriend that is only with me. I don't want to dump her after wasting all this time on her and then just not fuck her but I will if she tells me she won't have sex or if she wants to be with other guys.

I need you're opinion on what to do. I'm not scared about what will happen but I want to make sure I waste as little time as possible and lose my virginity as soon as possible.

Also thank you TRP. You saved me from being the most beta person I've ever known.
