<human>: This is a throwaway, because some of my friends know my real account.  There is this girl that I've liked for as long as I can remember, and we briefly dated when we were 15/16. Now we are both 18, and I have been unable to commit to any other people, I believe it's because I am still attracted to her. She has had other boyfriends, two I believe. Whenever she breaks up with a guy, she always comes back to me. 

Now before you all shout friendzone, when I say she comes back to me, I mean we start "talking" and doing things "friends" don't do. Yet, it seems like she always ends up with someone else because she doesn't want to ruin our friendship. 

It is not happening again, and I do not how to deal with it.We've been "talking" for around two months, which is long for our standards. She says she's serious about it this time, but obviously I'm thinking she is bullshitting me.  I haven't been able to have a relationship since freshman grade because of this girl. I am now a senior. Reddit, what do I do?

Can you provide a brief overview of the text?
<bot>: Girl I've been obsessed with forever keeps playing me, but I always hope she isn't, how do I deal with it?
