Pretty self-explanatory title.
The mod in question is syberspunk's Ask About Relationship Status Interaction.
I'd love to be able to use it if so!

Thanks in advance!

Did you have some problem using it with AL? Custom social interactions are just custom objects, they don't override any existing game code, and so they don't really have to be updated for new EPs any more than a custom couch does.

It works. I've used it.

Anyone he isn't in love with? XD

I had no idea! Thank you for your and Bulbizarre's input on this love your mods btw!

I use this mod and it does work, but I have noticed that with AL, the option doesn't show up on apartment neighbors. It says in the description that it only works on visitor sims who don't live on the lot, so my guess was that perhaps with it being made before AL, the modder didn't anticipate you'd ever have sims who live on your lot but whom you don't control? But yeah, it works but if you want to ask your apartment neighbor if they're dating anyone, you might have to catch them on a community lot instead!

Odd, as I had it work in an apartment lot with neighbours. Apartment visitors are a bit weird though, so it's not surprising.
