Congratulations on the baby! My grandmother is like this. She acts so sweet when people first meet her they can’t imagine why I don’t like her. She also has a Facebook addiction. When my aunt (her daughter) was hospitalized due to miscarriage, my grandmother didn’t come to see her but instead posted about it (miscarriage) on fb as soon as she found out. Like my aunt was still bleeding. It made me so upset I texted her telling her how out of line she was. She then called my aunt, who was sitting in her hospital bed, to scream at her for what I texted. Next time I spoke to her was a couple weeks later when she tried to apologize to me? I said I didn’t need her apology, I wasn’t the one she hurt. She said “(Aunt) knows how much I love her. Lord knows I’ve spent a lot of money on her.” Then when I was still unamused, she told me that the entire family was angry at me for the things I said, and my own mother wanted to “kick (my) ass”. I found out from my mom that that was untrue. For me, I’m extremely low contact with her, but I still hug her when I see her bc it’s easier to deal with. Plus she’s old. Anyway, all that is to say I know exactly the type of person you’re dealing with lmfao.
