Long post, sorry.
My 20-year-old niece is over from US for a few months. She stayed with us (on our sofa) for a couple of weeks and then moved into lodgings a half-hour bus ride away. I told her she's welcome back any time, for dinner or to stay the night. So far so good. She said she was very keen to keep in touch and particularly excited that she'd be able to spend time with my mother/her grandmother who has been extremely unwell. While she was staying with us, I invited her to a club I run. Since she moved out about 6 weeks ago, she's still been coming to my club but doesn't engage with me during the evening, just sits with other people she's got to know and basically ignores me. Now this club is literally minutes from my mother's and she gets there at least an hour early every week but doesn't ever pop in to see my mother, and doesn't ring her either. My mother asks me how my niece is, and knows she goes to the club, and is a little hurt by the fact that she doesn't keep in touch with her. I found out recently, via two different people, that my niece has moved lodgings although because she never contacts me I wasnt aware of the fact. This week my sister (niece's mum) asked me for her address (niece doesn't talk to her mum much either, it seems) and I had to admit I didn't know it. I've been upset by the fact that my niece doesn't seem to want anything to do with me, my family or my mother/her grandmother ( she's had basically no contact since she moved out other than at my club and we dont talk there anyway) and this week I called her out on it. Unfortunately she didn't come to the club this week (I found out from a third party that she was moving again) and so instead of a face to face conversation I sent her a message instead which was a terrible idea. She's now furious with me, saying I shouldn't be telling her what to do (true, probably), she's really family orientated (I see no evidence of that), I've been really unfair, etc. etc. I'm now torn between being convinced I was right to say something (mainly because I wanted her to see my mother who is very old, in poor health and virtually housebound), and knowing I've handled the situation badly. What on earth do I do now?
