But I know many, many more less happy cases.

For certain if you do this get EVERYTHING down on paper business-agreement-wise.

Feelings, and relationships, change. “Stuff” (possesions, property, etc) is far more fixed.

Protect your money; protect your friendship. It’s a hard balance. When it works, terrific… when it doesn’t, disaster.
