Is there a way to quickly end unwanted romantic relationships?

@RoseRyder it was still working for me as of last night. I’ve had to use it extensively to restore my sim’s relationships after moving my game to a new save. You have to be very careful with typing it all in exactly. Modifyrelationship YourSimFirst YourSimLast TargetSimFirst TargetSimLast number LTR_friendship_main. Number = -100 to 100. Substitute LTR_Romance_main to cheat the romance bar. Sometimes hyphenated names and multiple names (Like Mary Sue) are a problem with this cheat.
