Growing Together Negative Thread

The relationship chemistry concerns me a little. I have enjoyed actually being able to make decisions about who my sims date and marry without the complications of an attraction system like in Sims2. All the descriptions talk about friendships rather than romance, but they can't usually get romantic without some friendship first. I've been working to marry all the premades into my families for a while and I don't want those decisions taken away.
Hopefully that feature will come with a toggle, but even after the patch my sims still have fear moodlets when wants and fears are turned off so my faith in toggles has declined somewhat.
