My widower uncle was in a relationship with women who was as pleasantly sweet and accomodating as imaginable, and was completely consistent with this until the very end. He didn’t know the cohabitation laws where we live. Literally on the day of the three-year mark when common-law marriage entitlements kicked in, she filed for divorce. That’s the way the law works where we live -he had no idea that three-year cohabitation is treated identically to marriage, and that assets are divided equally. They were only in a relationship for less than four years, but she essentially forced him to sell his farm and pay her half, while his adult daughters lost half of their inheritance.

The woman was delightful all the way until the day -no warning signs as far as expression of dissatisfaction goes, no fights whatsoever, no complaints. It was the plan all along, and she was literally just counting down the days from day one.
