TS4 Lovestruck Positive Thoughts Discussion

I haven't purchased lovestruck. By design, my married and couples in relationships are very committed to each other.  I'm worried that lovestruck would destroy their relationships if I'm not playing them.  I also don't want any of my Sims to be attracted to anyone else except for their spouse or Sim they are in a relationship with.    

This pack does have features that I would like to have in my game; but, I will not risk the committed relationships I've established.  My game is in a good place in this regard.  

From everything I've read, there doesn't seem to be a way to turn off this feature in the pack.   It would be nice if they would tweak the settings so that if one isn't actively playing a household, they would maintain their own love. 

I just can't handle every couple's love turning into an Edward and Juliannna.
