Yes, my whole game got lovestruck, lol. Or stuck... rather, with the lag. I didn't try bienchens mod that you linked no, I was not aware that one existed. I suspect that I would have to use that mod from before lovestruck was installed though for the game to not have already done all those log entries for all sims.
I noticed that with lovestruck sims at the gym kept doing an autonomous flirty interaction where they show off their muscles. They did it a lot.
I moved the Lopéz family to Oasis Springs (including Manuel). They look a bit different in my game because I gave them a bit of a makeover and it was difficult to find similar items for some of them.
I found that mod not so long ago during checking her update. I use tons of her mods just to stop unacceptable "by design" functions. This mentioned mod isn't essential for me at that time, but then I heard your issue, I think this mod fits your case.
I think you may try once when you have time... to test using this Bienchen mod before install Lovestruck EP with your old save file to see if it's lagging or not. Just do it as a sandbox test. Testing this may help you know if it's still worth re-adding Lovestruck. (This EP has lots of nice CAS and B&B in my opinion, and the world is beautiful.)

By the way, your Lopéz (plus Manuel) is so nice! Although they can't be the same, you are still able to keep their charm! Manuel's shirt is a great choice that the vibe is almost resembles the original one. Their house also fits with Oasis Springs. You can let them live like this even without Lovestruck.
