Our parents died and she has treated me badly over their will, sorting out their estate and selling the family home. She been obstructive at every stage, demanding and selfish. I've tried to sympathise with her as she was very reliant on our parents financially and emotionally. We are both in our late 40s. I've done all the paperwork and got no thanks whatsoever, just criticism. I do love my sister but to be honest I've been on the verge of a breakdown over it. It's been going on for just over 2 years. The house is about to sell but she's deliberately being slow to sign documents etc.
AIBU to step away from her once the legal stuff is settled.
