My elder sibling has made my life miserable off and on since I can remember. We are in the process of selling the family smallholding as both my parents have passed away. Sibling is angry that the house and grounds have to be sold (won't go into details but the will means it has to be sold). The endless comments making me out to be the bad one is really too much. Sibling is dragging their heels with the estate agents etc and trying to prolong things. We are both executors so I can't walk away. I can't take the stress. AIBU to expect some cooperation. Sorry if this is garbled nonsense but I'm on the edge of a breakdown over it.
