So right essentially was sleeping with this girl this time last year till january when she turned up to a house party I invited her to with another dude. Over christmas I had decided that I actually quite liked her and was going to tell her till a number of things happened in my life. My friend went into a coma and lost her leg, my mums cancer was "coming back" (its gone again now), couldn't get a job, blahblahblah. When this sort of thing happens, I shut people out and thus stopped communiticating with her. Thats when she came to the party with the random dude.

Anyway, they had a relationship. My issues got resolved and being mature I acknowledged that I couldn't simply jump back into her life so left it alone. Over the course of this year shes had 2 different boyfriends with each one it has slightly felt like shes been purposefully shoving it in my face then flirting when they're not around.

Over the summer she started messaging me asking me if she could come round and chill. I was busy a lot and couldn't so I invited her to a party I had around mine last night. She turns up, everything is good all the usual "havent seen you in ages", "how are you" blahblahblah.

Anyway at some point and by this point I was fairly drunk and she had had a fair amount of coke we went for a smoke in the garden which was empty. I started telling her a story about a guy we both know but she cut me off:

Her: Were me and you just sex?
Me: what?
Her: Were me and you just sex, I'm asking as people keep calling me a slut and saying I was a bitch to you but I thought we were just sex. Did you think the same?
Me: Yeah...I mean I considered us to be friends.
Her: Oh yeah but was it just sex as well?
Me: Well yeah I did think that.
Her: ah good...
*long pause here, looks away then bursts out crying like a fucking waterfall*
Me: what the...why are you crying? whats wrong?
Her: I can't do it, I don't like lying to you. I really liked you and I know what I did was wrong but you just disappeared and people keep calling me a bitch about what I did.
Me: Okay...I haven't said anything to anyone that would put you in that light.
Her: I don't care about that. I spent so much time crying about you. Please don't let it have been "just sex."
*here she got insanely close*
Her: Please just tell me 100% truthfully now I'll believe you, was I just sex to you.
Me: I can't answer that question.
Her: why not! I miss you, I miss chilling with you. Was it just sex.
Me: I can't answer that question whilst you've got a boyfriend. I don't answer questions like that with words anyway, I'd just show you.
Her: What would you show me.
*At this point I'm half hugging her as I'm a sucker for crying girls, no idea what it is but I think its hot as fuck but anyway at this point she start pushing her chest against mine and catching hands, leans into my ear*
Her: The sex was fucking incredible.
*At this point I'm doing everything I can to just not kiss her but I'm not a dickhead, I don't fuck other guys girlfriends especially if they're a nice guy, Its happened to me, fuck making someone else feel like that.*
Me: This needs to stop, you have a boyfriend, he's a nice guy!
Her: I know...but if I could go back and change what I did I would.
Me: We can be friends, if you miss chilling then come round and chill.
Her: I know that I wouldn't want to just chill with you.

The rest of the conversation is a bit of a blur but essentially ended with a sort of half hug half cuddle thing so I could just stop her from crying. She admitted to me that a lot of stuff she did even with other guys was just to get my attention. Shes still confused as to why my friends hate her and is worried that I say bad things about her. I reasurred her that I didn't then we went inside.

and this is where shit got weird. After about 30 minutes of peace, i'm talking to some other girl then this girl grabs me and pulls me into the toilet.

Her: Why do your friends hate me!?
Me: Look, I haven't said anything and to be honest I don't think they do.
Her: I don't think you had said anything but you know them well, why do they hate me. I know they do.
Me: They have never said anything bad about you to me (they have)
Her: Please just tell me!?
*this went on for about half an hour then I just left the toilet, opened the door and one of the 2 girls that she thinks hates her is there.*

Her: Why do you hate me, please tell me. Seriously all I ever wanted was for you guys to like me.
My friend: I don't hate you.
Her: You do, why do you hate me? Me and *my name* were just sex, why do you hate me???

Apparently that went on for an hour. I disappeared with some people to another room. Then my friend comes in and sits next to me.

My friend: That girl is fucking crazy.
Me: she's okay, just a bit drugged up at the moment.
My friend: no she's fucking crazy, she's only trying to find out if me and *other friend* told you to stop seeing her. She doesn't want to be my friend at all. Why would she ignore me when I tried to say hello in shops and such when you weren't there. She only talks to me if you're around and its to find out why I hate her.

Then the girl came in and just acted normal with everyone else. Tears had finished, normal with everyone then just left with her friend who was pretty much passing out.

The reason I'm posting this is just to

1) what the fuck happened. What does she want, is she just an attention seeker/drama queen?

2) What do I do to stop it happening again. The more I seem to ignore her the more she seems to get like this. I can't not see her as she gets invited to the same parties that I go to, if she finds out i'm going to a club she's going to she'll message me/approach me when I'm there.

3) Am I just fucked?
