[LS] Sim who has never been heartbroken died of broken heart

My sim is dying of a broken heart when they shouldn't.  I am doing serial romantic aspiration.  I am doing you can call reserve 100 baby or knock up the townies.  My sim has the uncommited trait.   The romantic boundaries are set to no jealousy.   I had this problem since lovestruck.  New game play is with a fairy sim.   My sim goes on a blind date and dies after woohoo or at end of date.  Game should either have a toggle or smart enough to know with either the uncommitted trait, serial romantic aspiration or jealousy selections in create a sim that they can't die of a broken heart.
