As a non-parent it sounds about normal to me

My Mum will only 'phone us on a Monday morning. If I ring she'll be quite 'off' even if it's something important. She rarely rings my sister, however, my sister - according to Mum - only rings her when she knows Mum is out.
DH rings the moment he arrives somewhere or if he is going to be late ........ because I'm a worrier. His mother told me: but only me

: the day after F in L's funeral - "I won't ever ring you you know" ....... then the rest of the family walked into the room. I didn't know if she meant she wouldn't ring me personally or us as a couple

- but by God I found out

......... even when family members died she never let us know, it was other people who did so ....... I waited a couple of years before telling DH what had been said, I'd been watching her .....
How much are you hurt by them not being in regular contact?
