Bit of back story. I was with exh for 9 years. I left him when Dd was 3 months old when he was arrested for downloading indecent images of children. I maintained a good relationship with ex mil. She would visit every other week to see me and Dd. Always bought Xmas and birthday presents for us both.
However over the last couple of years she has stopped visiting. At first obviously due to covid. But then her other son had a baby and since then she has hardly bothered with us. I made the effort a few times suggesting we go and visit her etc. For the last 2 years she's literally dropped presents off for Xmas and birthdays. No messages in between. I got tired of trying to keep the relationship going. The last straw came this year when she didn't message on dds birthday. Instead sent a message over a week late asking if she could take her shopping for presents. I replied saying we busy (which we were) and she didn't reply. It just annoys me that she drops by twice a year and spends a couple of hundred pounds (not an exaggeration) then buggers off.
Anyway, I'm moving in with my partner next week and was wondering whether I should even bother telling her. Or just wait until she decides to message at Xmas. I do feel a bit bad because she's lovely. But if she's not going to bother with her first grandchild then why should I?
