Not in Sims 4, but in Sims 2 I had such a big crush on Lisa Ramirez. So I broke her and her husband up. Then my Sim married her. Then he fathered two children with her and I regularly invite Checo (her ex-husband) over just so I can show off our awesome children to him and make fun of him. Then I turned his daughter against him (Yes, when the two broke up I had Lisa take Tessa with her) and showed just how much of a better father he was by getting Tessa into a private school and getting her several scholarships. Also, did I forget to mention that Lisa dumped her husband, the furniture salesman for my Sim.....The Mayor? I mean honestly can you blame Lisa? Moving on from a furniture salesman to the Mayor? Who wouldn't?!
Oh speaking of the furniture store....I burnt it down. 7 people were trapped inside. Checo must live with that guilt. Also, I don't play his household (I moved him into a trailer) so he lives forever, forever to deal with all the awful stuff that has happened in his life because of me. And when he does die?.....I'll have him resurrected as a zombie slave of my Sim's son. Oh wait, I don't feel bad for him.
