On sims 2 how do you get married?

presumably he same as on other sims games, you build up your relationship with the sim you want to marry and then when you have the relationship value needd it will let you choose propose when selecting an action to take when you select that sim,

You buy the arch wedding thingy, and click it and it says "get married" if my memory serves me correctly. But, the person must be there, so you must invite them over or throw a wedding party and invite them. They must already be engaged also.

I figured how to engage. Where would you get the person from ?

Where would you get what person from?

Well presumably there are other sims around?

I guess somebody in my posts mentioned the preacher.
