How do you get a sim to leave another sim at the altar in sims 2?

I've had to do this many times ...

you need to have those to sims fight fight fight . and eventually , they will wanna break up . you will know when you click on your sims yu click

1. click on your sims
2. click on irritate
3. argue

eventually... this will happen...

1. click on your sims
2. click on FIGHT
3. click on BREAK UP

then once yu click on that , your sims will break up . one of your sims will move out of the house . but then yu can always play them because they are in the bin with the families that have no home yet(=
