**No. Miis can't cheat in Tomodachi Life.** In both Living the Dream (Switch) and the 3DS game a Mii has one partner at a time, and nobody can fall for a married Mii in Living the Dream or the US and European 3DS versions. The closest thing is partner stealing: a single Mii can confess to a Mii who is dating, and an unhappy sweetheart may say yes.

## Cheating, stealing and rivals in each game

| | Living the Dream | 3DS game |
| --- | --- | --- |
| Secret affairs | No | No |
| Two partners at once | No | No |
| Single Mii falls for a dating Mii | Yes, usually rejected | Yes, usually rejected |
| Dating Mii leaves for the confessor | Possible when the couple is on bad terms | Possible when the couple is on bad terms |
| Anyone falls for a married Mii | No | No |
| Love rivals at a confession | Yes | Yes |
| Breakups and divorce | Yes | Yes |

The 3DS column describes the US and European versions. The Japanese 3DS version is the exception: there a married Mii could be confessed to and won over, according to the Tomodachi Life wiki.

## How a sweetheart gets stolen

Both games handle it the same way, and the wiki documents the steps:

- A **single** Mii falls for a Mii who is dating someone. In Living the Dream this is a crush you are asked to approve.
- The single Mii asks to confess. You can say the crush is already taken, which makes them sad, and a Mii with a strong crush may confess anyway.
- The taken Mii answers. If things are good with their sweetheart, the answer is no. In Living the Dream they say outright that they are dating someone.
- If the couple is on bad terms (around "Kinda getting along" or lower) and the taken Mii likes the confessor, they can say yes. They switch partners on the spot with no breakup scene, and only the Mii who was left becomes sad.

That is a public swap, not an affair. No Mii ever dates two Miis at once or hides a relationship. Sims Community's romance guide for the Switch game saw attached Miis turn confessions down and concluded that Miis don't get wandering eyes.

## How to protect a couple, or stir things up

- **Keep the couple close.** Stealing only works on unhappy couples. Drag them together often in Living the Dream. On 3DS, a trip with a travel ticket lifts their relationship by one or two levels.
- **Fix fights fast.** A fight that is never patched up can end in a breakup request. Calm both Miis with things they like, then help them apologize.
- **Stop the rival early.** In Living the Dream, answer **You're imagining things** when a Mii starts crushing on someone who is taken. The crush ends and the Mii doesn't get sad.
- **Marry them.** Nobody can develop a crush on a married Mii in Living the Dream, and nobody confesses to one in the US and European 3DS versions.

Want the drama instead? Do the reverse: approve the rival's crush, leave the couple's fights alone and let their relationship sink. The game still decides the ending.

One blunt tool exists in Living the Dream: changing a Mii's dating preferences so that the pair no longer match ends the romance and turns them back into friends, as Sims Community reports.

## Breakups, divorce and exes

Couples also end with no third Mii involved. When a relationship is low, one partner tells you they want to break up, and you answer:

- **Living the Dream:** "for the best" or "think about it some more". The first ends the relationship. The second starts a talk with the lights off that either saves the couple or ends it.
- **3DS:** "move on" or "work things out", with the same two outcomes.

Sweethearts can also part calmly and stay friends, with no sadness. Married Miis can divorce. In Living the Dream couples with children ask less often, and on 3DS a couple raising a baby can't divorce at all. Exes avoid each other, but the relationship list includes a "Would try again" level, and a Mii may ask to get back together.

## FAQ

### Can married Miis cheat or be stolen?

No. In Living the Dream nobody can develop a crush on a married Mii, and in the US and European 3DS versions nobody confesses to one. A marriage ends only in divorce, never through a rival. The Japanese 3DS version did allow confessions to married Miis.

### Can a Mii have two crushes at once?

Not in Living the Dream. A Mii holds one crush, and if feelings start for someone new you choose which one they pursue. On 3DS a Mii can tell you they like two Miis, and you pick who they confess to.

### Why did my Mii leave their sweetheart for someone else?

Their relationship level had dropped, and another Mii they liked confessed. In that case the taken Mii can accept and switch partners straight away. Keeping a couple's relationship high prevents it.

### Do Miis get jealous?

There is rivalry. In both games rivals can burst into a confession and ask the target to choose. In Living the Dream, two friends with a crush on the same Mii can end up in a fight, according to the Tomodachi Life wiki.
