We have a bit of a rocky relationship - we've never really seen eye-to-eye on things. She has always been financially irresponsible and relies on our parents for money (she's 23) which always annoys me. She refuses to take responsibility for her actions, it's always someone else's fault, she doesn't see why she might be the problem. Has had about 7 jobs in as many years (there's always a problem with the people there/she ends up falling out with colleagues because 'they're bitchy', and so on and so forth). She has been given SO much help both financially, physically and mentally over the years (from me, parents and her ex-BF) but always fritters it away, and then the cycle of 'I have no money, can you lend me some' continues.
My main gripe is that she asks to sleep at mine at LEAST once a week. I have a small one-bed apartment and I'm an introvert. I don't mind hanging out with her but I don't see why she needs to sleep at mine so frequently. Her reason is always "I'm lonely/I feel emotional/I don't want to be on my own/it's easier if I stay at yours because you're closer to my work" and I can't help thinking YOU'RE AN ADULT. Learn how to be on your own for more than a week without asking for a sleepover.
She's not a particularly good guest either - will sit on the sofa ALL day watching stuff on my laptop, sleeps completely naked sprawled out on my bed, asks that we don't open the curtains so we're stagnating in the dark all day.. the list goes on.
WIBU to tell her that no she can't stay over, that I want my own space? And that we're adults, you can't just have a sleepover when you feel a bit sad? (In a slightly softer way!)
