I don't quite know how to read this one.
Because of various upheavals in the wider family I spent a lot of time looking after one of my relatives when she was a child. She also lived with us on and off in her late teens and early twenties.
She is married now and lives in another part of the country. I try and keep in touch with her, but not by ringing her landline. She works long hours and she's out or else tired.
But I don't have a smartphone - just an old fashioned PAYG one.
Most recently after someone who was close to her died, I sent her condolences via email plus a couple of scanned photographs where she was with this person.
She didn't reply at the time or later. Next time I saw her I asked whether she got the message and she said, 'Oh it must have got lost among the junkmail. Just text me another time.
So I said that I mainly just text for urgent stuff, but that with some other people I use FB Messenger.
To which she said, 'Oh I use FB even less. I suppose I ought to better at sorting through my junk.'
In my situation would you feel that she just didn't want much contact with me any more. (It hardly seems worth getting a smartphone just to be in touch with someone who basically wants to let things drop.)
