Before I start I just want to say that I want nothing with this girl and that this is not a case of oneitis. It is just an observation I made.

Ever since I met her, she's been open and friendly to me and we really just clicked. She was in a relationship for quite some time(~6 months). After some drama, they break up. You know, the usual story: guy's a piece of shit, guys are such jerks, she was the perfect girlfriend etc. She's an amazing friend, but is a bit oblivious to her narcissism.

Some time passes and she all of a sudden starts throwing herself at me. I figured nothing good would come out of this for either one of us, and there are a lot of reasons as to why it is a bad idea (don't shit where you eat, social stigma is real in high school etc).

That's the backstory. The next part is what confuses the shit out of me.

After a while she figures out I want nothing to do with her and moves on. We go back to our usual friendship.

Then she gets a boyfriend.

Goes 180 on me. Stops speaking to me, no texts, no calls, nothing. And at first I found this to be very odd so I distanced myself as well.

Not a week passes by, she starts hitting me up again. Turns out her bf left her. It seemed a bit strange, but I decided to give her another chance. Two weeks pass by and this girl finds another guy and grows distant once again.

What is so weird to me is that she's totally open and friendly with every other guy (and girl), but starts ignoring me whenever she gets into a relationship.

Is she just one big case of attention whore or am I missing something here?
