This is one of things i hope does not return in Sims 4, unless they are planning to do it properly and go back and adjust all there premaids. In Sims 3 i watched a previously happy couple with 5 kids, suddenly with seasons or generations (can not remember which) decide they prefer every other Sim they met of the opposite sex instead. I played on epic life spans so both had max skills in many things. Attraction was only awarded to new Sims, not old relationships. Being awarded not compatible zodiac signs did not help ether, i think that was Late night.
Playing Pleasentview in Sims 2 i also encountered the same problems, Don and Daniel where attracted to each other as both where assigned attracted to facial hair. In Sims 2 you could fix it when you rotated around but not every one does that in 3 or 4.
This is something i would love in base game but introduced afterwards, has very mixed results. In 4 all Sims are bisexual which means every other Sim besides the spouse, would be more attractive.
If they where introducing Sims 2, 1 sided attraction, for skills I could sort of live with it, but would still prefer not. If it would be the 2 sided attraction of Sims 3 where my skilled Sims found every lazy, slob attractive, never seriously no.
