So my grandma passed and is giving an inheritance. My mom (70) said she would split her share with me (35f) and my sister because my mom is already worth quite a bit of money. She said I would be getting a specific amount for a LONG time, I’m talking pretty much my whole adult life. This is not is my g-ma’s will, my mom was just going to do it. Now that’s it’s actually time to do it, she doesn’t want to split it and only give us a certain amount. She has done this in the past too, like “oh I’m gonna give you $5,000!” out of the blue, without asking, and then later when she is about to write the check, “so I was thinking I should only give you $1,000.” Fine whatever, don’t look a gift horse in the mouth. But now she’s trying to change her mind on $100,000 and I’m not happy. I said to her that she said we were going to split and that’s the way it’s been for a long time. She claims she doesn’t remember, her defensive technique, and now she’s not happy with me. AITA for bringing it up, or should I just be happy that she’s still willing to do it? Side note about why I was relying on the money… I was diagnosed with arthritis and a myriad of other this at 25 so I’ve been “maintaining” my health until I could get this money. With the amount she wants to give now I could easily spend half just feeling better… Am I the idiot for relying on this money to get my health in order? I’m so conflicted….
