You live with a man for several years now.
You're not married.
He cheats on you.
Yall break up.
During the time yall were together he had a major illness caused by hospital negligence and almost dies.
He has a pretty good case.
His lawyer contacts you for a deposition.
You call your ex and tell him you'll only do it if he agrees to give you half of the settlement.
He doesn't agree so you steadfastly REFUSE to do it.
Was this reasonable?
