Here's some backstory: A little over a year ago I met this girl at a friend's party. She was kind of cute, but the thing everyone liked about her was she was insanely busty. About a month later I saw her again at another party, and we made out. Later on that month we went on 2 dates. The only problem was on the second date she got WAY too drunk, and I ended it early and I sent her home. She was acting like a lunatic, and since she made a bad impression I called it off with her. But she kept popping up in the picture since we have a ton of mutual friends.
A few months after that we got drunk and ending up hooking up again, and we decided to do a FWB situation. It's been fine for the most part, but lately she's been wanting to go out and get dinner, or change our relationship statuses on Facebook, and recently she said she wanted to meet my parents. I keep telling her no fucking way, I don't want a relationship (In general, it depends on if a better girl comes along). We had a talk about this, and she suggested calling it off if we couldn't agree. I told her that was for the best, but as soon as I said that she changed her mind and wanted me back.
It's almost a year now since we first hooked up, and she's been talking about an "anniversary". I absolutely don't want to celebrate anything with her. She's a cool chick to party with, but that's it. I can't see myself having anything serious with her. In fact, I've been hooking up with other girls the entire time but haven't told her. I just don't see her as being anything other than a chick I get drunk with and then fuck.
But no matter how many times I try and get rid of her, she refuses. I don't want to do anything brash like tell her I've been with other girls, but I feel like that would be the only way to get rid of her. She has many of the same mutual friends as I do, so a lot of the times if I don't plan on seeing her she's there anyway with some of my other friends.
And I feel like zero hour is approaching. One positive about her is that her dad is really rich, and she buys me drinks and food when we go out. My birthday was this summer, and she bought me really expensive tickets to see one of my favorite bands. I was all for it when she got them for me, but now I'm afraid that she's going to try and push things further after the concert.
So, any advice on what I should do?
