How to complete the life time wish "gold digger"

create your sim. Active the cheat "testingCheatsenabled true" without quotations of course.
Then type in "freerealestate" Pick a lot, don't need to worry about the money. Complete a 
few wishes in order to gain some lifetime points. Once you have 5,000 points, purchase the
observant reward. The observant reward allows you to figure out 3 of a sims traits 
automatically upon greeting them, in addition, you get to see if they're rich. Locate your
rich sims, find out their names. Once you have a name (a target) press shift and click on 
the mailbox at your house. Choose the option "Make me know everyone". The game might freeze
for a moment, but it should be temporary. Once unfrozen, check you relationships list, under
all and find them rich sim you want. On the bar below their picture, drag their bar all the 
way up on the right side (it should be green, making them your best friend). Now that you're
best friends, put the moves on this sim, even if they're married, but don't let their spouse
see. Once you've done enough romantic actions, you can request that they leave their spouse.
Once they leave their spouse, entertain your target. Woohoo with them, try for a baby if you
like. Afterwards, propose marriage. If they say yes, go for it. Have the wedding, a private 
ceremony or a party, it doesn't matter. Once you're married, kill the rich sim in any way 
you like once you grow tiered of him. Make sure the sims with the gold digger trait is 
around when he dies, so you can see their ghost and fufill the gold digger wish.
