If you are adults, have a one on one open discussion on what the issue is. Go ready to listen not to accuse/attack. If you’re minors, do the same with an older, objective sibling/cousin or young adult with you two as a mediator. Leave the talk with an understanding the issue and a resolution to be friends or not, and move on.

We talking sibling? Parent? Or outside the immediate household. If it’s outside the household cut them off. If it’s inside, seek counseling.

Get really drunk and be toxic back, behave so badly you never get invited to anything family related ever again. No one is going to side with you they like the other family member more. If the family member who you think is toxic has the most money you are well and truly fucked. Blow up the family and move on they will never side against the money
