NC for this, mum has dementia, coming up is a milestone birthday and I have just found out my SB has booked a holiday and is taking her and his dad away, apparently did not register it was going to be her birthday, me and my other sibling have only just found out as we were planning on doing something.
For context, our SB was off the scene for a lot of years and only over the last fews years has he resurfaced. I do not trust this man one little bit, I don't trust his motifs. He says he is trying to help, which he has, but has practically took over and is getting involved with banks, financial advisors, has copies of all their finances, stocks, bonds, everything to 'help them out for when my mum needs to go in a home'. Trying to sort out LPOA but dads digging his heels in and don't think mum has capacity to sign it.
I've asked him to move the dates and he's said no. I just feel like this is another way to take control.
AIBU? Should I just suck it up and let them enjoy the holiday or should I stop sobbing (which i have been doing since I found out) and kick off
