Is emotional abuse okay?Watch
You might want to also try talking to your mum on her own if your dad won't change the record.
Hope that helps.
My gran died a couple months ago, and my other grandparents are the same to me, they've told me I'm the reason for my parents fighting, my mums also fed them a bunch of lies about me, and then my uncle has skin cancer and I don't want to add to his stress, we have quite a close family weirdly, it's just I'm not really sorry involved in it. Thanks anyway I may reach out to my uncle and cousins if he gets better
Condolences for your loss.
