here is a hypothetical scenario that may or may not be based off my life! (i am going insane someone please give me advice)

imagine this: you have a best friend of 11 years and you're incredibly close, with how close you were people always assumed you were related! however, around 7th grade or so she starts changing a lot, you don't think much of it because whatever life happens and you were also changing. She gets her first ever boyfriend around this time! Wow! You're so happy for her! However, they break up after a while. 1st semester 8th grade rolls around and you two get roped into some weird homoerotic friendship and kiss each other a few times and she's VERY adamant on dating you so you accept! HOWEVER she finds another boyfriend and you're obviously hurt like what the fuck aren't we dating???? She tells you "Oh, don't worry about it, it's just to make my dad not be suspicious." you foolishly believe her and have to spend her entire birthday following her and her boyfriend around while they make out passionately every 10 fucking minutes. 

2nd semester of 8th grade rolls around, highschool entrance exams are coming up and she breaks up with her boyfriend around that time. You, being the good friend decide to comfort her! Not even a week later she finds a new one, and wow would you look at that! The relationship didn't even go past the 5 month mark! He ended up being a drug dealer! You finish the highschool entrance exams, you get a whopping 90/100 and get into one of the best highschools in your country! She gets into a rather shittier highschool but it's fine! 

You notice she began ignoring you, how weird. And then she starts talking about how many friends she has made in just two months while you were still trembling and almost crying whenever a classmate of yours approached you. You began feeling jealous, so you kinda started avoiding her. However, yet again, you decide that wasn't fair for her since you were best friends for such a long time and you reach out once more. Everything is fine! And she gets a new boyfriend, amazing! This one was a really nice and smart guy, you were sure they'd date for at least a minimum of 5 months before she breaks up with him and finds a new boyfriend after a week. You began noticing she only begins to call you to hang out just so she can see her boyfriend, since her dad is a little bit strict when it comes to dating (and rightfully so, she sucks at picking out guys). You obviously feel a littttle bit pissed, because you make time to see her just so she can meet up with her boyfriend.  

They break up again, her boyfriend calls you at 2am crying and asking you what he did wrong for her to break up with him so suddenly. You reassure him that maybe she just fell out of love, dating comes by quickly and goes by just as fast and whatnot. You don't have the heart to tell him that she's going to replace him in a week minimum. 

August of 2026 rolls around and she finds a new boyfriend, who she quite literally started dating the day they met. And oh God.... She always calls you to hang out just so she can see him without consequences, makes out with him all of the time to the point you're sure they'll just start having sex with each other in the middle of the street if they continued on like this. And not even that! She sends you videos and photos of them together, cute right? Well, it would be but it's just videos of them making out and doing other suggestive things together! You, unfortunately, are not a voyeur so you don't get much out of this. Not only that, you explicitly said you were uncomfortable with what she was doing and she did not give a fuck! 

What would you do in this situation?
