Which Relationship Cheat Sims 4 Commands Reset Relationships Entirely?

I've wrestled with relationship drama in 'The Sims 4' more times than I care to admit, and the cheat that actually lets you wipe the slate is the modifyrelationship command — used to zero out both friendship and romance tracks. First, enable cheats with testingcheats on (or testingcheats true). Then either use names or grab Sim IDs with sims.get_sim_id_by_name FirstName LastName if you prefer IDs.

Concrete example with names: modifyrelationship John Doe Jane Doe 0 LTR_FRIENDSHIP_MAIN and modifyrelationship John Doe Jane Doe 0 LTR_ROMANCE_MAIN. Do the same in reverse (modifyrelationship Jane Doe John Doe 0 LTR_FRIENDSHIP_MAIN and modifyrelationship Jane Doe John Doe 0 LTR_ROMANCE_MAIN) because relationship values are directional and sometimes hidden bits persist otherwise. If you used IDs, the syntax is the same except with numbers: modifyrelationship 123456789 987654321 0 LTR_FRIENDSHIP_MAIN, etc.

A couple of practical notes from my gut-level testing: resetSim only resets a Sim’s physical state and bugs, not their relationships, so don’t expect that to clear romances or friendships. Also, there’s no single vanilla cheat that nukes every relationship in the entire save at once — you either do pairs manually with modifyrelationship or use a mod to batch-clear. Always back your save up before doing mass edits: I once cleared a long-running family tree by accident and swore for a full coffee break. If you still see odd lingering interactions after zeroing the main tracks, try clearing specific relationship bits with extra modifyrelationship calls or check for active situations that might be re-adding ties.

If you want a less tedious route, using a reputable mod (I’ll mention specifics separately) can mass-reset or selectively remove ties. For casual cleanups, the name/ID-based modifyrelationship with LTR_FRIENDSHIP_MAIN and LTR_ROMANCE_MAIN is the most reliable built-in method I’ve used — just be patient and methodical, and keep a backup save so you can roll back if something goes sideways.

I tend to be the practical, shortcut-loving type, so when I want to wipe relationships in 'The Sims 4' I reach for a mod called MC Command Center (MCCC) rather than doing dozens of manual cheats. MCCC has relationship management tools that let you reset, remove, or scale relationships across households or the whole save — which is a lifesaver when you've inherited a legacy world full of messy ties. Install the mod, go into the MCCC menu (usually via a Sim), find the relationships section, and choose the option to clear or reset relationships. It’s much faster than typing modifyrelationship over and over.

That said, if you prefer native cheats the core built-in approach is: testingcheats on, get Sim IDs with sims.get_sim_id_by_name, and then use modifyrelationship 0 LTR_FRIENDSHIP_MAIN and modifyrelationship 0 LTR_ROMANCE_MAIN — repeated for both directions. Either route works; I just favor MCCC when there are dozens of Sims involved and I want to avoid human error. Always back up your saves first, though — learned that the hard way during a dramatic family purge.
