I don't know what to do. Recently I was befriended by someone who just won't leave me alone. She's really hard work, I don't particularly have much in common with her, I find her views on life tedious and boring, she's selfish, and none of my 'real' friends like her.

The fact is she's quite lonely and vulnerable and for that fact only I feel I can't just tell her to piss off.

She's constantly asking me to go here there and everywhere with her and even invites herself along to things that I'm going to with other people (who also don't like her).

I've let her down on numerous occasions in the hope that she will 'get the hint' but she never has. I've actually been out with her for the past two weekends and now she's pestering me to go out with her this weekend too. I've already made my excuses.

HELP!! she's driving me crazy! How can I get her out of my life without appearing callous and uncaring? (I'm scared she would do something stupid)
