Is this said AFTER he's come and you're regretting it?

It can be both, it's not clear here.

Ah

Elena, you realize that OVER implies to your house, right?

Also, “I wish he didn’t come” is habitual: every day, all the time, while I’m working...

“It would be better if he didn’t come” in the future or habitually.

Removed "over' since it's not clear here ...

It's not clear in this phrase, habitually or at a particular occasion

So if your husband comes to see you at work every day and it embarrasses you, you could tell someone this in Russian?

Yes, possible.

Gotcha!

Мой муж каждый день заезжает ко мне на работу, и мы возвращаемся вместе домой. И каждый день он приносит мне цветы. Все женщины на работе мне завидуют. Лучше бы уж он хотя бы в отдел ко мне не заходил.

Some interesting expression
I just as soon...

Interesting and misunderstood! Most native English speakers think they hear “I just assume” and use this continually 😅

what to say about the foreigners...

At least they have an excuse!

In Ngram there are only examples with this expression equivalent to
"I prefer doing sth."

About YOU doing something or SOMEONE ELSE doing it.

Ir's interesting, thank you.I'll look into it tomorrow...

Yes, by all means, don’t take my word for it!

THAT’S interesting (I didn’t ask you what you thought of it, you’re volunteering that comment)

Uly., it was 1 a.m. and my head refused to work, that's what I meant... please don't be offended, I'm very thankful to you for all your help 🌝

I wasn’t offended, I literally meant that you should research that expression yourself because I use it naturally, but I don’t know the grammar behind it.

That's good :).
This phrase in a sentence seems so illogical to me...
I've looked it up. So, the synonyms are "I'd rather", "I'd sooner".
I'd rather you hadn't come. I'd sooner he didn't come. Right?
I've never met such constructions before.

Yes. Here’s a better example. Third paragraph: https://www.ctaudubon.org/2018/10/member-profile-judy-wilkinson/

Elena, didn’T
