I have to sims that I originally wanted to be together but now and I don’t and they are engaged help.
I can relate to this. I don’t know how you can break off an engagement, but the closest advice I can give you is that you let them get married. Don’t worry though, this is all apart of the plan. You interact with their spouse, go to the rival options and there should be a “Divorce” option that takes like 59 min. :D
Can you have a dog in Sims 1, 2, 3, or Mobile or only on Sims 4
go to rival events, then go to divorce :)
u go to the sim u want to make an ex and go on rivalry if it's not there then pick one of the opshions (can be random) and a thing should show up saying devorse. (p.s sorry for my spelling) good luck
