DM recently told me that a few years ago she gave a significant amount of money to DB. I completely understand why she did it at the time. However life has moved on, his problems have resolved and he has offered to pay her back, but she has refused.
The reason she told me is because she's doing her will and wanted to tell me I will get an additional amount when she dies so it's fair. And then joked she will probably live another 20 years and all her money will go on care home fees.
We are not great financially atm (CV related) which she well knows. DB is now in a far better position than us, and lives a much nicer lifestyle in terms of cars, holidays, home improvements etc.
If we weren't struggling financially, or if DB simply couldn't afford to pay her back it wouldn't bother me but right now I'm quite upset. DM knows our situation and could easily afford to help us out a bit and has made noises about doing so but it's always very vague and never materialises. To be clear, I have never, and would never ask her for money.
I'm not going to say anything to her as it's her money etc etc but would this upset you? It's left me feeling really second best and right now I don't want to speak to either of them.
There is no golden child dynamic going on as far as I know, I just don't think she has in any way thought that this would feel like favouritism or that it would upset me. I just wish she hadn't told me tbh!
