Traduzione - Russo-Inglese - Мне без тебя так трудно жить,а ты все дразнишь и...

"You can’t take the place of the whole world for me but it seems that you can " I didn't understand this part. Would you please explain? Thanks in advance.

OK, I'll try to say with other words.
It's something like: "You can't be everything for me but it seems for me that you can be."
And now can you understand?

I can't.

Could it be:

"You are not supposed to be everything to me, but it seems to me ( I feel) that you can be" ?

No, Lilly, "You are not supposed to be everything to me" has the other meaning.
Now I'm looking for some other words to explain the context of the sentece better.
Is it possible to wait a bit and not reject my translation?

You cannot replace (?) the entire world (for me), but it seems that you can. Maybe something like that

What about:

"...you shouldn't be my entire world, but it seems you can."?

Bravo Lilian I like it.

Yes, Lilly, you are right it's better, thanks a lot

It's "can't" as "not able", "not possible".
