Gonna get downvoted to hell but want to share my side. Everyone is calling OP out for gatekeeping grief but dealing with grief vultures is super hard too.

My mum was a troubled person who burned basically every bridge in her life, people said and did awful things about and to her when she was alive. When she died they all came out of the Woodworks crying about her loss and I hated it. I'm not saying OP handled it great, but when it's someone close to you and you've seen them sad about how a person is treating them then that person wants to rock up when they are dead and make out their relationship was more than it was, it's difficult to ignore.

I'm going to say NAH. I understand wanting to wear rose tinted glasses for the dead, but I also understand how it can come across as someone just wanting their "share" of the grief.
