My nieces mum has blocked me on things after a bit of a row the other day, she was saying I don’t put any effort in to see her which really hurt me because I’ve always felt I did what could in the circumstances. It was my nieces birthday party yesterday and me and my children didn’t go as it didn’t feel like the right thing to do. I have tried to drop off her birthday gift at her mums house but nobody was in after trying twice. I don’t know how to handle this, I have messaged her apologising but because I am blocked she won’t see it.
