I'm after a little bit of advice if possible.
Back story is my biological father walked when I was a baby out and didn't look back. I got in touch with him in my mid teens and we had an awkward, strained relationship for about 18months then he walked away again.
Six (ish) years ago I had a message on facebook from my 13 year old half sister, he did the same thing to her 13 years after me and is pretty much just a giant waste of space.
So sister and me have been in touch ever since, I find her quite difficult to talk to sometimes and I wouldn't describe our relationship as being close, though I would like it to be. It's always been a bit one sided which was fine when she was a kid, except she isn't anymore. She's 19, she moved close to me about 7 months ago, I sorted her out with benefits, I paid her deposit, the only thing I asked for in return is that she got a job or went to college. She has done neither!
She sits around all day doing naff all, she says she want to come over but always manages to miss the one bus, I live in the middle of nowhere and there is only one bus a day, but then she expects a chauffer, it's 11 miles but by the time I've sat outside her place for 10 minutes it's an hour round trip, I have a job, a husband, two kids and she cant make the effort to be up and dressed and on a bus at 2pm. What the hell? But the worst thing is she says she's coming, and then doesn't, she says to the kids she's coming and then she doesn't. But she doesn't even tell me, so I've sat here today waiting for her to rock up like a prize pickle and no sign at all, so I ring, then I ring, then I ring again - nothing. Then I send a sh*tty message on Facebook, she reads it, then nothing. Half an hour later she sends 'sorry'.
I give up! This is not just once, this is constant, she's like a bit lost, and a bit depressed, ffs I'd be depressed if I sat around all day with the curtains closed tapping on my phone with no one to talk to. But I cant keep doing this with her, I've cut our idiot father out for just this very inconsiderate, want to be part of your life on minute, cbfa the next, I'll make promises I have no intention of keeping, I'll twist the truth to suit me crap, and it's like she's got too much of his lazy crappy attitude in her. Aside from this I have quite a normal family and maintain good relationships with all of them (even the in-laws most of the time) so I don't understand why this is so hard.
