Which do you save?

Person A: is destined to save your life in return though this makes your future partner believe you are cheating on them and your partner leaves you and you never see them or person A again and are forced to be forever alone.

Person B: is destined to be your future partner whom will love you with all their heart or till you become a drunk driver and end up going to jail because you got in a crash and killed someone, while in jail you may not receive visits or anything and are forced to be alone...till you drop the soap.
