How do I know if another player approves of his/her sim moving into my household?

I have asked for approval ones, weeks ago and never got feedback. Never was told that it was denied either. Same as we never get a rejection notice on friend requests either. They realy should change this. If you see this player online and his/her sim has not moved in het, it's save to asume your request was denied. I'm making my own sims ever since.
